The 3548 is one of two standard references — alongside the sub-seconds 3716 — built in the case style collectors call the "Empire" Oyster: classically round, 32mm, but with elongated, rectangular, sloped lugs distinct from the hooded-lug treatment most Bubblebacks of the period carry. Specialist research on Rolex's early Oyster case history documents the type as chronometer-certified and automatic throughout, placing it firmly inside the Bubbleback family despite the case's unusual silhouette.
The 3548 is documented alongside the sub-seconds 3716 in the case style collectors call the “Empire” Oyster. The cited examples are round, about 32 mm, with elongated sloped lugs rather than the hooded-lug profile common on many Bubblebacks. Specialist case-history research describes the group as automatic and chronometer-marked; the auction records here establish those details only for the individual lots.

"Empire" is a collector name, not a Rolex one, for a specific case profile: round rather than tonneau, but with distinctively elongated, sloped, rectangular lugs in place of the hooded-lug style common across the rest of the Bubbleback range. The 3548 is documented as the centre-seconds standard reference in this case style, paired with the sub-seconds 3716; a rose gold variant of the same case appears on the related 3877. All are documented as 32mm, round, and automatic — the "bubble" in Bubbleback refers to the domed caseback the automatic rotor required, present regardless of the lug treatment.

A steel example sold at Antiquorum for CHF 9,375 (lot 477); a second steel example, movement no. 93792, dated circa 1943 by Bonhams, sold at the house's Paris sale on 24 May 2022 (sale 27810, lot 268) for &euro;3,570. A rose gold example of the sibling case style (ref. 3877) sold at Antiquorum for over 50,000 CHF against a 6,000&ndash;10,000 CHF estimate — more than five times its high estimate — underscoring how sharply the market has moved on well-documented "Empire" case examples in recent years.

A rose-gold example of the sibling case style, ref. 3877, is documented separately in the auction record. Its sale does not establish a price rule for steel 3548 watches.

Self-winding, chronometer-certified. The Bonhams-catalogued example specifies a jewelled automatic movement, numbered 93792.
The cited auction records describe automatic movements, and Bonhams records movement number 93792. The chronometer wording belongs to the individual dial or catalogue description; no caliber number is published for the lot.

The Bonhams-documented example carries a salmon (orange-toned) dial: black Arabic numerals for the hour markers, a black outer track dividing fifths of a second with Arabic 5-minute markers, blued steel pointed baton hands, and gilt centre seconds — a notably colorful dial treatment next to the silver and black dials more common across the wider Bubbleback range.
The Bonhams-documented example carries a salmon or orange-toned dial with black Arabic numerals, a black outer fifth-second track with Arabic five-minute markers, blued pointed baton hands, and gilt centre seconds. Those details describe that lot; they do not establish a complete 3548 dial inventory.

32mm round stainless steel case, brushed and polished finish, screw-down case back and crown, and the elongated rectangular sloped lugs that define the "Empire" style. The cited 3548 examples share the round case and elongated sloped-lug profile. Other Oyster references from the period should be compared from their own case records rather than assumed to share this silhouette.

32mm round stainless steel case, brushed and polished finish, screw-down case back and crown, and the elongated rectangular sloped lugs that define the "Empire" style. Rolex's earlier manually-wound Oyster cases of this general period showed considerable variability in shape; the automatic "Empire" Bubblebacks were built to this one consistent silhouette.
