The Seastar T120.607.11.041.01 (aka: T1206071104101), seen from the bench

The Tissot Seastar T120.607.11.041.01 evolves a collection founded in 1951 for ocean performance. This 46mm professional watch features a stainless steel and ceramic case with a C07.111 quartz movement, delivering chronometric precision and multi-year accuracy. The dial displays hours, minutes, seconds and date with clear readability. The 22mm lug width is determined by fixed lugs welded to the case and requires precise measurement for strap compatibility.

Frequently asked questions

What is the lug width of the Tissot Seastar T120.607.11.041.01?

The T120.607.11.041.01 features a 22mm lug width, determined by the internal distance between the two fixed lugs soldered onto the case. This specification requires watchstraps manufactured precisely to this width, without adaptations or forced adjustments that could compromise the lug finish or wrist comfort.

Which watchstrap is best for the Tissot Seastar T120.607.11.041.01?

The optimal choice depends on intended use. For everyday elegance and urban versatility, vegetable-tanned calf leather in cognac or black tones offers balance between aesthetics and durability. For serious aquatic activities, an FKM rubber or polyamide NATO strap guarantees resistance to chlorine, salt, and UV radiation. For aesthetic excellence, authentic alligator elevates the case presence without stylistic overload.

How do you change the watchstrap on the Tissot Seastar T120.607.11.041.01?

Strap replacement requires a spring bar tool to gently extract the spring bars from the lugs. Position the tool in the bar groove, push laterally to disengage the terminal hook, and rotate the bar downward. Repeat from the opposite end. Exercise caution to avoid scratching the ceramic case or crystal dome. Perform the operation on a soft surface.

Is there an aftermarket watchstrap compatible with this Tissot model?

Yes. Any watchstrap engineered with a 22mm lug width is compatible with the T120.607.11.041.01, provided the strap shoulder geometry aligns with the case. Artisanal watchstraps, constructed with precise tolerances, offer material quality superior to generic alternatives and demonstrate proven longevity. Verify dimensions before purchase.

How long does a vegetable-tanned leather watchstrap last?

A high-quality vegetable-tanned leather maintains structural functionality for 4-7 years of daily use, depending on care applied. Prolonged exposure to water, unwiped perspiration, and direct sunlight accelerates aesthetic deterioration whilst maintaining fibre integrity. Regular maintenance—rapid drying after humidity, conditioning with specialist creams every 6-12 months, protection from heat sources—significantly extends strap lifespan.
