Strap for PRX Powermatic 80 Rose Gold / Blue

The lug width of the Tissot PRX T137.407.33.041.00 is 12mm. This measurement is specific to the model and determines compatibility with aftermarket straps. To verify it, measure the distance between the inner lugs where the strap attaches using a calliper or millimetre ruler. It is a precise measurement with no tolerance for variation.

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.

Changing the strap on the Tissot PRX T137.407.33.041.00 requires a specialised tool to extract the spring bars. Proceed carefully: position the watch in a watchmaker's vice, press the internal spring of the bar with an extractor or dedicated lever, extract the bar and remove the strap. Repeat on the opposite side. When installing the new 12mm strap, ensure the lugs seat flush against the case without lateral play.

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.

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.
