PR 100 T101.210.22.031.00 (aka: T1012102203100)— lug 16mm

The lug width of the Tissot PR 100 T101.210.22.031.00 is exactly 16 millimetres. This measurement represents the internal distance between the two lugs (case attachments) where the watch strap is inserted. This parameter is critical for compatibility assurance: standard straps measuring 18mm or 20mm will not fit correctly on this case. You can verify the measurement using a digital calliper positioned perpendicularly between the two lugs, or by consulting Tissot's official technical specifications.

The optimal strap selection depends on your intended use and aesthetic preferences. For formal occasions and maximum refinement, an alligator or full-grain vegetable-tanned calf leather strap represents excellence in execution. For daily versatility, a dark brown calf leather strap creates elegant visual contrast with the silver-brushed case. For practicality in humid environments, a polyamide NATO strap or satin-finish rubber offers water-resistance and maintenance simplicity. Each selection modifies the perceived character of the timepiece: consult Milano Straps' catalogues to identify the tone and material that best align with your personal aesthetic.

The strap on the Tissot PR 100 T101.210.22.031.00 is changed using a standard tool called a spring bar tool. Procedure: position the watch in a dedicated support bracket; locate the lateral lugs (anse) of the case; gently insert the flat end of the spring bar tool into the lug hole to compress the internal spring; remove the tool's tip from the passage of the old strap; insert the spring bar tool into the passage of the new strap; press until the spring bar clicks into its housing. Repeat the operation for the second lug. If you lack experience, a professional watchmaker will complete the operation in minutes without risk of damage.

Yes, high-quality aftermarket straps are fully compatible with the Tissot PR 100 T101.210.22.031.00, provided they respect the 16mm lug width specification. Milano Straps offers a specialised collection of straps in vegetable-tanned leather, alligatore, shell cordovan, NATO, and technical rubber, all manufactured in standard 16mm sizes and available for rapid dispatch. An aftermarket strap allows you to transform the aesthetic identity of the watch, transitioning from formal elegance to sporting versatility, whilst maintaining the watch's performance integrity. The quality of materials and the finishing of the passants determine overall durability.

A quality natural leather strap (full-grain calf, alligator, shell cordovan) maintains optimal performance for 3–5 years under moderate daily-use conditions, provided regular maintenance is observed. Factors influencing longevity include: direct solar exposure (accelerates ageing), elevated humidity (promotes degradation), frequency of wear (daily use reduces lifespan compared to occasional wear), and tanning quality (vegetable tanning is more robust than chrome tanning). A strap exposed to tropical humidity may degrade in 18–24 months, whilst one stored in temperate climate and worn infrequently may exceed 7–8 years. The patina that develops over time signifies material nobility, not degradation. Maintenance includes periodic cleaning with a damp cloth and application of watch-specific leather balms.
