FAQ
What is the lug width of the Tissot Seastar T120.217.37.041.00?
The lug width (ansa width) of the Tissot Seastar T120.217.37.041.00 is 20 millimetres. This measurement represents the distance between the two lugs of the case, measured orthogonally from the centre of one to the other. It is essential to verify this measurement before purchasing any aftermarket strap, as an incorrect tolerance would result in unstable bayonettes and imprecise fittings within the strap lugs.
What is the best strap for the Tissot Seastar T120.217.37.041.00?
The optimal strap depends on intended usage. For formal elegance, we recommend alligator leather with vegetable tanning, in black or dark blue tones, which complements the dial's minimalism perfectly. For durability and zero-maintenance, a vulcanised rubber strap in black guarantees unlimited water resistance. For versatility, a NATO strap in canvas blue-white preserves the sports heritage of the model. A black calf leather strap with deployante represents the ideal compromise between aesthetics and daily practicality.
How do I change the strap on the Tissot Seastar T120.217.37.041.00?
Strap replacement requires the removal of the spring bars that secure the strap to the lugs. Use a dedicated spring bar removal tool or a small flat-tip screwdriver. Position the watch on a soft surface, gently press the spring bar laterally to disengage the bayonette from its seat, then remove the old strap. Insert the new strap, ensuring both bayonettes lock correctly into the designated holes on the lug. Repeat for both sides.
Are aftermarket straps compatible with the T120.217.37.041.00?
Yes, all artisanal straps with a 20mm lug width are compatible with this reference. milanostraps.it offers a comprehensive collection of leather straps (alligator, calf, cordovan), textile NATOs, rubber straps and bespoke solutions. Each strap is supplied with appropriately-sized lugs and soldered bayonettes, guaranteeing precise fitting.
How long does a leather strap last on a 38mm watch with daily use?
Lifespan depends on the quality of tanning and frequency of use. A quality vegetable-tanned leather strap can withstand 3–5 years with regular maintenance (cleaning, occasional conditioning). Shell cordovan is more durable, reaching 6–8 years. Constant exposure to moisture, perspiration and UV rays accelerates ageing. A rubber strap, conversely, maintains structural integrity for 4–6 years, with gradual aesthetic wear but no functional failure.
