Strap for Tonda Metrographe Stainless Steel / White / Bracelet

The lug width of the PFC274-0002400-B33002 is 18mm. This parameter is critical for strap compatibility and must be measured precisely between the vertical attachment lugs. An incorrect lug width results in strap instability or impossibility of installation.

The optimal strap depends on intended usage. For formal contexts, a cognac or black alligator in vegetable tanning emphasises the case's sober geometry. For versatile daily wear, satinised rubber with stainless steel deployante offers practicality without aesthetic compromise. A grey or dark blue NATO represents the modern solution for those appreciating dynamic styling.

Strap replacement requires a specialised tool called a spring bar tool or extractor. Position the watch on a stable surface, insert the extractor into one of the lateral lugs to release the internal spring, then extract the pin. Replace the strap and reinsert the pin, verifying that both ends of the spring are correctly engaged.

Yes, all straps with an 18mm lug width are compatible with the PFC274-0002400-B33002. It is essential to verify that the strap is constructed to high standards, with robust stitching and finishing appropriate to the usage context. Artisanal leather straps or technical rubber ensure durability and aesthetics befitting the watch's prestige.

A high-quality leather strap (alligator, vegetable-tanned calf) on daily-worn timepieces has a durability of 3-5 years before replacement. Factors such as climate, frequency of wear, and maintenance (avoiding prolonged exposure to excessive moisture) significantly influence longevity. Satinised rubber lasts 4-6 years; NATO straps have similar durability but show greater resilience to environmental conditions.
