Tissot Seastar, Ref. A660/760K, Cal. ETA 2846, Men’s Automatic

Vintage Tissot Seastar Automatic from 1990 is a Men’s Swiss Made watch powered by the ETA 2846 caliber, combining a silver dial, gold-tone applied markers, a framed day-date display and a stainless steel case. Offered for sale with refined late-20th-century character, it is completed by a new brown textured leather strap.

Tissot Seastar A660/760K — restrained 1990 wrist presence

The 36 mm case and 41 mm lug-to-lug measurement give this Seastar compact, balanced proportions that suit its dress-oriented design. A polished round bezel surrounds the broad silver dial, while sculpted lugs and small gold-tone accents add visual definition without making the watch ornate. The 18 mm strap width keeps the case and leather in proportion, producing an easy-wearing profile for buyers who prefer traditional sizing.

Silver dial with concentric center detailing

The dial has a pale silver finish with fine concentric rings around the central area, creating texture that becomes more apparent under changing light. Applied gold-tone baton markers define the hours, including doubled markers at several positions, while small pale circular accents sit near the track. The TISSOT 1853 signature is placed beneath 12 o’clock, and Seastar, AUTOMATIC and 21 JEWELS appear above 6.

Framed day-date and gold-tone handset

A prominent framed day-date aperture occupies 3 o’clock, displaying both weekday and numerical date in a single horizontal window. Slim gold-tone hour and minute hands echo the applied markers, while a fine central seconds hand completes the three-hand layout. The result is a practical calendar display integrated into an otherwise open and orderly dial.

Stainless steel case with polished and gold-tone accents

The confirmed stainless steel case uses a rounded profile with flowing lugs and a polished bezel. Small gold-tone decorative details are visible around the case and crown area, tying the exterior to the warm dial furniture. Light age-related surface marks can be seen under close inspection, but the case retains a bright overall appearance and the original architecture remains clearly defined.

Ridged crown and practical calendar control

The crown sits at 3 o’clock and has a pronounced ridged edge for secure grip during time and calendar setting. Its gold-tone finish adds another visual connection to the markers and hands. No crown signature is clearly visible in the supplied image, so the listing does not describe it as signed.

New brown textured leather strap

A new brown leather strap with an embossed texture is fitted between the 18 mm lugs. Its warm color complements the gold-tone dial details while contrasting with the stainless steel case. The adjustable fit makes the watch straightforward to wear, and the strap is clearly treated as a replacement component while the watch itself is confirmed as retaining all original watch components.

ETA 2846 automatic caliber with 21-jewel dial signature

The movement is confirmed as the ETA 2846, an automatic Swiss caliber that powers the watch’s time and day-date indications. The dial visibly states 21 JEWELS, allowing that specification to be included without assumption. The watch is listed as serviced and fully operational, giving the mechanical specification direct relevance for ownership.

Seastar design at the beginning of the 1990s

Dated to 1990, this example combines established Swiss dress-watch proportions with a more contemporary two-tone visual treatment. The silver dial, gold-tone furniture, sculpted stainless steel case and day-date display create a composed style that can move easily between formal and everyday use.
