Reference 1490 is a rectangular Rolex Prince with a flared Brancard case, a duo-dial with subsidiary seconds at six, and an Aegler shaped movement. Auction and archival records document steel, 9K, 14K, and 18K gold, pink-gold and two-tone cases, and one platinum example. The reference appears in records from the 1930s through the 1940s; exact production boundaries are not published. | |||

The Prince | The Prince launched in 1928 with an Aegler shaped movement and rectangular cases. Early references include the 971 and related models; the 1490 is a larger flared case variant.

The Prince and | The Prince and Oyster lines ran in parallel during the 1930s. The Oyster Perpetual became Rolex's main round-case platform after 1931, while Prince examples continued into the 1940s.

Prince › 1490
Reference 1490 is a rectangular Rolex Prince with a flared Brancard case, a duo-dial with subsidiary seconds at six, and an Aegler shaped movement. Auction and archival records document steel, 9K, 14K, and 18K gold, pink-gold and two-tone cases, and one platinum example. The reference appears in records from the 1930s through the 1940s; exact production boundaries are not published.

Where it sits in the line
The Prince launched in 1928 with an Aegler shaped movement and rectangular cases. Early references include the 971 and related models; the 1490 is a larger flared case variant. A 1930 Rolex advertisement uses the phrase "the watch for men of distinction," but that slogan is period advertising rather than a technical description.
The Prince and Oyster lines ran in parallel during the 1930s. The Oyster Perpetual became Rolex's main round-case platform after 1931, while Prince examples continued into the 1940s. A 1947 caseback dedication is evidence for one late example, not a published end date for the reference. The 2005 Cellini Prince is a separate modern watch and is outside the 1490 reference history.
Brancard, or just Prince?
The name Brancard is used inconsistently. Phillips, Sotheby's, Bonhams, Antiquorum, and Christie's use it for 1490 auction lots, while Michael Friedberg's 2001 TimeZone article and Coronet Magazine's 2021 article reserve it for the earlier 971. The reference number is less ambiguous than the nickname.
The 971 is the earlier flared Prince, and the 1490 uses a larger version of the same case idea. Calling the 1490 Brancard follows current auction-catalog usage, while older collector writing may use Brancard for 971. The naming difference does not change the reference number.
The case, Brancard stretcher
The 1490 is a three-piece rectangular case with a flared profile; Brancard is French for stretcher. Published measurements vary because some catalogues measure the body or bezel and others include the horn ends. The body is roughly 36–37 mm long by 22–23 mm wide; measurements including the horns reach about 42–43 mm in length.
The case flares at the lug ends and narrows toward the centre. The lugs are integrated into the case and use through-pins for the strap. The crystal is acrylic with a step-edge profile.
The crown is push-pull and signed Rolex. Gold cases carry gold crowns; steel cases carry steel Rolex crowns. A steel crown on a gold case is a service compromise, period-correct in execution sense but not original to the watch.
Case materials

Published auction records document the following 1490 case materials:

- Stainless steel, including the 1937 Bucherer-double-signed Sotheby's example and a 1936 Bonhams example. Double-signed retailer examples should be separated from unsigned examples when comparing auction results.
- 9K yellow gold, including Glasgow-assayed 1930s examples at Bonhams and Antiquorum.
- 9K bi-color (yellow + white gold), documented at Antiquorum 2006 lot 324, Glasgow 1931.
- 10K yellow gold, reported by collectors but not represented in the auction-catalogue sources listed here.
- 14K yellow gold, documented in the T. Eaton 1/4 Century Club examples (Antiquorum 2010, c.1945).
- 18K yellow gold, multiple Sotheby's and Phillips lots, including Phillips NY080223/92 from 2023 (case 13,009, c.1933, hammer USD 17,780).
- 18K pink/rose gold, documented in Antiquorum 1990 lot 278 (pink-gold/steel two-tone).
- 18K bi-color "Tiger Stripe" (yellow + white gold), Antiquorum 1995 lot 274 (CHF 24,150) and Bonhams August 2020 lot 7Y (estimate GBP 9,000–12,000).

The Tiger Stripe nickname is also applied by some catalogs to other Prince references (notably the 971A); it is not exclusive to the 1490.
- Steel + 18K pink gold two-tone, Antiquorum 2006 Mondani lot 46 (case 17,365, 1935, hammer CHF 38,940).
- Steel + 9K yellow gold two-tone, Antiquorum 2009 lot 461 (case 1010 / movement 76,529, Glasgow 1930–31, hammer CHF 19,200).
- Platinum, one documented example in Bonhams December 2017 lot 135Y, circa 1930. A single lot does not establish total surviving production.
The movement

The 1490 uses an Aegler shaped movement made in Bienne. The shaped-movement family was developed by Aegler with Hans Wilsdorf and was used for the Prince from its launch. Rolex's later 2004 acquisition of Aegler is outside the production history of this reference.
Published 1490 catalogues identify several Aegler movement attributions. The following assignments are tied to the cited examples and should not be treated as a complete factory register:
- Cal. 300, 15 jewels, 18,000 vph, approximately 50 hours of power reserve, produced 1928–1937. Rolex Magazine and Watch-Wiki attribute Cal. 300 to base Prince examples. Cal. 300 and Gruen Cal. 877 are related Aegler shaped movements sold under different brand names; some early literature labels Prince examples Cal. 877. The catalogues cited here do not provide a single universally accepted naming rule.
- Cal. 350, 15 jewels (some examples 18 jewels). Documented on the Phillips Beyer-double-signed steel 1490 (CH080319/17, c.1930) and on Phillips NY080223/92 (18K, c.1933). The 350 appears alongside 300 across documented examples without obvious dating segregation; both calibers run inside the same case reference.
- Cal. 7½′′′ T.S. 300, 18 jewels, lateral lever escapement, monometallic balance with micrometer regulator, Breguet overcoil hairspring, rhodium-plated, adjusted in 6 positions, produced 1932–1938. "T.S." is Rolex's own size-family code for this 16.9 × 32.7mm architecture (Christie's catalogues it as "cal. T.S. Ref. 300"); the commonly repeated expansion "Très Soigné" has no documentary support. This is the Ultra Prima movement variant, documented on the Mondani Collection 1490 at Antiquorum May 2006 lot 46 (case 17,365, 1935). The T.S. 300 is the highest grade of the shaped-movement family deployed in the 1490.
Movement grade is separate from caliber number. Published 1490 examples are described as Prima, Extra Prima, or Ultra Prima; those labels refer to finishing, adjustment, and testing claims in the cited catalogues. They do not by themselves establish a complete grade distribution:
- Prima: a Cooke & Kelvey (Calcutta) steel example c.1930 sold by Rolex Passion Market.
- Extra Prima: the Sotheby's Bucherer 1937 (17 jewels), the Heritage 5177-60121 18K example labeled "Extra Prima Observatory" 15 jewels, and most published Bonhams examples.
- Ultra Prima: the Antiquorum Mondani 1935 example with T.S. 300 caliber, the fabsuisse.com Beguin example, and forum-confirmed examples on VRF thread 28392.
Some 1490 dials are marked "Chronometer" or "Observatory." The cited sources associate those marks with higher movement grades and observatory testing, but the surviving catalogue record does not support a universal one-to-one rule for every watch. The 1914 Kew certificate often cited in Rolex histories concerns an earlier movement, not a 1490.
The cited 1490 movements predate the shock-protection systems used in later Rolex calibers. The watch should be treated as a delicate vintage movement and protected from impact.
Dial variants

The 1490 dial is a duo-dial: two visually separated registers on the same dial plate, with the hours-and-minutes track in the upper portion and the small-seconds register in the lower (six o'clock) position. The seconds register has its own dedicated short hand running on its own pinion, driven by the fourth-wheel-at-six gear-train configuration that defines a sub-seconds layout (as opposed to the center-seconds layout used on some later Rolex references). The visual effect is two clean concentric tracks rather than the busier read of a single combined dial.
Dial signatures documented on surfaced 1490 examples:
- Rolex single-signed, silvered base, Arabic numerals (most common), with "Rolex," "Oyster" wordmark omitted (the 1490 is not an Oyster), "Chronometer" designation on Extra Prima / Ultra Prima examples.
- Rolex single-signed with Observatory designation, Heritage 5177-60121 (Extra Prima Observatory 15j, 18K c.1930s).
- Bucherer double-signed, Sotheby's Watches Online July 2019 lot 13. The Bucherer-Rolex retailer relationship dates from 1924 per Sotheby's catalog notes.
- Chronométrie Beyer Zurich double-signed, Phillips CH080319/17, the Beyer-Zurich 1998-renovation NOS example.
- Philippe Beguin (Geneva) double-signed, fabsuisse.com Beguin example, original Beguin-signed presentation box also documented.
- Cooke & Kelvey (Calcutta) double-signed, Rolex Passion Market c.1930 example, with the original Cooke & Kelvey box.
- T. Eaton 1/4 Century Club, Eaton's of Toronto issued 1490 examples to employees on 25-year service anniversaries, with a dial signature that replaced the Rolex name with "Eaton 1/4 Century Club" text. Almost uniquely among Rolex production, the Eaton 1490 dial carries no external Rolex branding. The earliest documented Eaton 1490 is from the mid-1930s; the latest is c.1945–1947, including the Antiquorum 2010 Walter Earnshaw example covering his 1920–1945 service.
Documented dial colors include silvered, two-tone sector-style, and black duo-dial examples. Hand styles include blued steel Breguet, pencil, pointed-baton, and épée forms, as well as gold leaf hands on some gold cases. Sub-seconds hands are commonly blued steel; replacement hands and refinished dials should be assessed against the individual watch.
Age-related foxing and refinished dials are both seen in 1490 material. A clean dial is not proof of originality; compare printing, hand aging, surface texture, and provenance against documented examples. Any price effect depends on the individual lot.
Authentication
Authentication should begin with the movement, case, dial, and their fitment to one another. Two useful checks are:
- Movement-to-dial pairing. Documented 1490 examples use Aegler shaped movements, including Cal. 300, Cal. 350, and 7½′′′ T.S. 300 attributions. A non-Aegler movement requires an explanation as a replacement or mis-cased watch. A caliber number alone is not enough; compare the movement architecture, grade markings, dial designation, and case evidence.
- Caseback engraving style. Period-correct 1490 casebacks are stamped at the factory. Hand-engraved caseback markings are the standard tell of post-factory work, either a re-engraving on a worn caseback or a replacement caseback engraved by a service shop. Owner-presentation engraving can appear on Eaton 1/4 Century Club and retailer-presentation examples; it should be considered alongside the factory stamping rather than treated as a factory reference mark.
The crown signature is a useful third check on cased examples. A gold case should carry a gold crown signed Rolex; a steel case should carry a steel crown signed Rolex. A steel crown on a gold case indicates a service replacement, period-correct in pattern but not original to the watch as built. Movement-only purchases (without case) should be cross-checked against the Aegler-family architecture before pairing with any 1490 case body.
Auction record
The 1490 has a substantial auction record across Antiquorum, Phillips, Sotheby's, and Bonhams. Selected results show how material, signatures, condition, and provenance affect the outcome:
| year | venue | configuration | hammer |
|---|---|---|---|
| 1990 | Antiquorum | Pink-gold/steel two-tone | CHF 7,475 |
| 1995 | Antiquorum | 18ct white + yellow Tiger Stripe | CHF 24,150 |
| 2006 | Antiquorum | Steel + pink gold, T.S. 300 Ultra Prima (Mondani) | CHF 38,940 |
| 2006 | Antiquorum | 9K bi-color, Glasgow 1931 | CHF 21,240 |
| 2009 | Antiquorum | Steel + 9K yellow, Glasgow 1930–31 | CHF 19,200 |
| 2017 | Bonhams | Platinum | GBP 32,500 |
| 2019 | Phillips | Beyer-double-signed steel NOS (1928 stock, 1998 found) | CHF 62,500 |
| 2023 | Phillips | 18K yellow gold, c.1933 | USD 17,780 |
| 2023 | Bonhams | Steel, c.1936 | GBP 3,584 |
| 2025 | Bonhams | 9K yellow, Glasgow 1930 | GBP 4,096 |
The selected results are not a price guide. Unsigned steel, double-signed steel, gold, two-tone, and platinum examples occupy different parts of the record, and condition, originality, case material, signature, and provenance all affect the result.
The Sotheby's L19070 lot 42 and Phillips NY080223 lot 92 both list case number 13,009. The records may refer to the same watch; they should not be counted as two independent examples without further provenance.
