Hard rule #10: drop the CHF 6,000 hammer from the intro — already in the Historical market and auction record table (Antiquorum Geneva lot 337)
Line 17: Line 17:
The 5701 is the two-tone Rolesor sister to the 5700 Air-King-Date. Same 34mm steel three-piece Oyster case middle, same Cal 1525 → Cal 1535 movement progression with date module, same date window at three under cyclops magnification — but with an 18k yellow gold fluted bezel and a gold crown in place of the 5700's all-steel construction. The 5701 is the date counterpart to the no-date 5501 Rolesor, running across the same Rolesor convention that the 5501 establishes on the no-date side. Where the 5501 swaps the 5500's smooth steel bezel for solid gold, the 5701 swaps the 5700's smooth steel bezel for solid gold — same trim swap, applied to the date variant.

The 5701 carries the cursive "EXPLORER-DATE" dial branch the 5700 also carries — small subset of production, predominantly North American market, early-to-mid 1960s. Antiquorum Geneva 29 March 2009 lot 337 (5701/1500 Explorer-Date, 1963, Cal 1530, hammer CHF 6,000) is the documented anchor. Antiquorum NY 2009 lot 71 catalogues a 1972 5701 Explorer-Date — the variant carries forward into the Cal 1535 era and isn't strictly a 1963-only configuration. Outside the Explorer-Date branch the 5701 trades through dealer markets at lower volume than the 5500-class steel Air-Kings; the 27-year production window plus the Rolesor pricing premium plus the niche date-complication market combine to keep auction visibility narrow.
