Frequently asked questions
What is the lug width of the Tissot Seastar T120.210.22.051.01?
The lug width of the Tissot Seastar T120.210.22.051.01 is precisely 18mm. This dimension is measured from the distance between the two vertical pins that anchor the strap to the case. It is essential to verify this measurement before purchasing an aftermarket strap, as the T120.210.22.051.01 requires straps specifically dimensioned for 18mm lug width.
Which strap do you recommend for the Tissot Seastar T120.210.22.051.01?
For the T120.210.22.051.01, we recommend alligator or crocodile straps in teak brown for formal wear, vegetable-tanned calf in navy blue or forest green for daily versatility, or vulcanised rubber for sport and diving applications. The choice depends on context: a cognac-brown alligator strap creates aesthetic harmony with the brushed stainless steel case finish, whilst a navy NATO offers practicality and strap changes without specialised tools.
How do I change the strap on the Tissot Seastar T120.210.22.051.01?
Strap replacement requires a spring bar tool (specialised lug pin plier). Position the watch on a soft surface, insert the tool into the small lateral hole of the lug pin, press gently to release the pin from its housing, then extract it. Repeat on the opposite side. To install the new strap, insert the pins into the lateral slots of the new strap, then use the tool to reinsert the pin into the case housing until it clicks. Avoid abrupt movements that could scratch the case lugs.
Can I fit an aftermarket strap to the Tissot Seastar T120.210.22.051.01?
Yes, any quality 18mm strap is compatible with the T120.210.22.051.01, provided the lug pins are correctly dimensioned (typically 1.5mm diameter). We recommend artisanal straps crafted from premium leathers—African alligator, shell cordovan, vegetable-tanned calf—to ensure superior aesthetic longevity and durability compared to generic commercial straps. Avoid synthetic leather straps, as they degrade visually rapidly and do not develop the characteristic patina of natural leathers.
How long does a leather strap last on the Tissot Seastar T120.210.22.051.01?
Leather strap longevity depends on material quality and usage conditions. Artisanal vegetable-tanned calf, worn daily, maintains structural and visual integrity for 18–24 months in temperate climates, extendable to 2–3 years with preventive maintenance (protective wax application, rapid drying after water contact). Premium alligator resists for 24–36 months. Shell cordovan, owing to superior cellular density, reaches 36–48 months. Vulcanised rubber straps retain functionality for 3–4 years before material hardening. Salt water exposure accelerates ageing; in marine environments, we recommend rubber straps or semi-annual leather renewal.
