FAQ

What is the lug width of the Tissot PRX T137.407.11.091.00?

The lug width of the Tissot PRX T137.407.11.091.00 is 12mm. This measurement represents the distance between the lugs (attachment points) that protrude from the case. To verify compatibility with an aftermarket strap, measure this distance precisely using a digital calliper. This precision ensures a perfect fit without lateral movement or play.

Which strap do you recommend for the Tissot PRX T137.407.11.091.00?

For the T137.407.11.091.00, we recommend alligator straps with vegetable tanning for an elegant, patina-rich aesthetic, Italian calfskin for a minimalist and contemporary look, or NATO and rubber for daily and sports-oriented use. The choice depends on your personal style: dark brown alligator creates a subtle dialogue with the dial, while burgundy calfskin or navy NATO adds personality without aesthetic compromise.

How do you change the strap on the Tissot PRX T137.407.11.091.00?

Strap replacement is straightforward: use a spring bar tool to remove the lugs, or contact our Casati Milano atelier for a bespoke service. Insert the tool under the lug sideways, apply gentle pressure to compress the internal spring, and slide the pin out of the case. Repeat on the opposite side. Your new 12mm strap installs using the same method in reverse.

Is a high-quality aftermarket strap compatible with the Tissot PRX T137.407.11.091.00?

Absolutely. The Tissot PRX T137.407.11.091.00 is one of the most receptive models to aftermarket strap customisation due to its standard 12mm lug width. We recommend ordering artisanal straps in noble materials (alligator, premium calfskin, shell cordovan) from specialised workshops. Milano Straps offers a comprehensive collection of 12mm straps ready to ship and customisable online.

How long does a leather strap last on the Tissot PRX T137.407.11.091.00?

A high-quality leather strap with proper vegetable tanning and carefully selected leather has an average lifespan of 3-5 years with daily use. Durability increases significantly if you alternate use with other straps. The patina that develops over time does not compromise functionality but enriches it aesthetically. To extend strap life, avoid constant moisture exposure and occasionally apply conditioning products specifically formulated for leather.
