This Omega Seamaster Automatic Ref. 166.087 is one of the more distinctive early-1970s Seamaster references, appreciated by collectors for its substantial tonneau-shaped stainless steel case, strong wrist presence, and unmistakable period design. Often informally referred to by collectors as a “Jumbo” Seamaster, and sometimes associated with the broader “Baby Flightmaster” visual language, the model reflects Omega’s transition into bolder, sportier case architecture during the 1970s. Case and Case Back: Stainless steel tonneau / cushion-form case with integrated-style lug architecture and screw-back case construction. The inner case back is correctly signed Omega Watch Co., Swiss Made, Acier Inoxydable, and bears the reference 166.087. The outer case back features the raised Seamaster hippocampus medallion. The case presents well, with visible but honest vintage surface wear consistent with age. Case Thickness: Approx. 9 mm Movement: Omega automatic movement Calibre: Omega Cal. 1002, a high-beat automatic calibre with quickset date and hacking seconds. Jewels: 20 jewels Frequency: 28,800 A/h Power Reserve: Approx. 42 hours Serial Number: 32032403, placing the watch broadly around the early 1970s. Dial: Original rare silver textured / linen-style dial with applied baton hour markers, date window at 3 o’clock, original black-filled hands, and a distinctive orange central seconds hand. The dial shows attractive and even vintage ageing, giving the watch strong character while preserving its original design identity. Crystal: Crystal in good vintage condition. Crown: Original Omega-signed crown. Strap: Brown vintage-style leather strap with Omega buckle, excellent condition. The buckle appears to be aftermarket. Total wearable length with case: approx. 24 cm. Dimensions: Case Diameter: 39 mm excluding crown / approx. 40 mm including crown Lug-to-Lug: 44 mm Lug Width: 19 mm General Condition: Professionally serviced and reported to be running strongly while keeping accurate time. A highly attractive and honest vintage Seamaster with strong originality: the case, dial, hands, crown, case back, and movement appear correct for the reference. Only the strap and buckle are modern replacements. Overall, this is a charismatic and collectible 1970s Omega Seamaster, combining a rare textured dial, jumbo steel case, and Omega’s Cal. 1002 high-beat automatic movement.
