This lot comprises two vintage Seiko wristwatches of differing movements and styles. The first is a stainless steel Seiko Bell-Matic automatic mechanical alarm watch. It features a black dial with silver-tone baton indices, a day and date aperture at the three o’clock position, and an internal rotating alarm bezel. The dial is marked SEIKO, BELL-MATIC, 17 JEWELS, and JAPAN 4006-6010T. The reverse of the case is stamped with the Seiko logo and reads STAINLESS STEEL, 4006-6011, WATER RESISTANT, JAPAN A, alongside the serial number 160790. It is fitted with an integrated stainless steel link bracelet, the clasp of which is marked STELUX and ALL STAINLESS STEEL on the interior, with individual links stamped PAT NO 1095305 and PAT NO 84801S.

The second timepiece is a Seiko quartz two-tone wristwatch. The cream dial displays gold-tone Roman numeral indices with a date window at three o’clock, marked SEIKO QUARTZ, S 50, and MOVT JAPAN 7N47-7A68 R 2. The case is constructed from stainless steel with a gold-tone base metal bezel. The case back is stamped ST. STEEL BASE METAL BEZEL, WATER RESISTANT 5 BAR, 7N47-7A00, and A4, with the serial number 462727. It is presented on a two-tone Jubilee style bracelet with a signed Seiko fold-over clasp; the end links are stamped 4173-G-E.


Condition report:

Both watches exhibit signs of age and regular wear. The Bell-Matic shows significant scratching across the acrylic crystal (photo 2) and throughout the stainless steel case and bracelet links. There is visible dirt and residue accumulation between the bracelet links and around the case back seal (photo 4, 6). The two-tone quartz model displays light to moderate scratching on the crystal and gold-tone bezel (photo 3). There is noticeable thinning and wear to the gold plating on the crown and the central bracelet links (photo 7, 8). The mechanical functionality and timekeeping accuracy of both watches are untested; the quartz model likely requires a battery replacement.
