What I'm asked about the Tissot PRX T137.407.33.041.00
What strap size does the Tissot PRX T137.407.33.041.00 take?
The Tissot PRX T137.407.33.041.00 needs 12 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Tissot PRX T137.407.33.041.00 be changed?
Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.
Can I put a leather strap on the Tissot PRX T137.407.33.041.00?
Yes, in 12 mm leather. On a 40 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Tissot PRX T137.407.33.041.00?
A 12 mm calf strap, for every day. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
Which strap material pairs best with the Tissot PRX T137.407.33.041.00?
The Tissot PRX T137.407.33.041.00 accommodates multiple material interpretations. An alligator strap emphasises the dress-sport character and creates elegant contrast with the metal geometry of the case. A vegetable-tanned calfskin offers contemporary styling and natural texture, whilst a NATO in cordura provides practical versatility. For a more sporty option, FKM rubber straps deliver comfort and resistance to daily wear.
Which aftermarket straps are compatible with the T137.407.33.041.00?
All straps with a 12mm lug width are compatible. Milano Straps offers a dedicated collection for this specific measurement, available in leather (alligator, calfskin, shell cordovan), NATO and technical rubber. It is essential to verify that the strap is designed for 12mm: generic adapters or straps in adjacent sizes (14mm, 10mm) carry risks of poor seating and premature wear to the spring bars.
How long does a leather strap last on a Tissot PRX T137.407.33.041.00?
The durability of a leather strap depends on leather quality, usage and maintenance. A high-quality artisanal alligator or shell cordovan strap, with regular care (occasional cleaning, protection from direct moisture), can last 5–8 years. A vegetable-tanned calfskin is more moisture-sensitive and requires greater attention but offers comparable longevity if kept in dry environments. Replacement is recommended when cracks appear in the grain or structural failure of the lugs occurs.
