Strap for PR 100 Sport Chic 36 Stainless Steel / Black MOP / Bracelet

The lug width (ansa width) of the Tissot PR 100 T101.910.11.121.00 is precisely 18 millimetres. This measurement represents the distance between the two watch lugs, from tip to tip, and is essential for selecting a compatible strap. It is important to measure accurately using a digital calliper, excluding the spring bars, to avoid confusion with other common sizes such as 16, 20, or 22 millimetres.

The choice of strap depends on your intended use and aesthetic preference. For formal and sartorial occasions, we recommend an alligator strap with vegetable tanning, which ages gracefully and develops a rich patina. For everyday versatility, a calf leather strap in warm caramel brown tones offers refined understatement. For sporting or marine environments, a NATO nylon strap or vulcanised rubber ensure water resistance and practicality. All these straps are available in 18mm size through MilanoStraps.

Changing the strap is a straightforward operation requiring no specialist tools. Position the watch face-down on a soft surface. Using a spring bar tool, gently push the spring bar towards the opposite side, releasing the strap from the lug. Repeat on the other side. Insert the new strap into the lugs, ensuring the spring bars are correctly aligned, and press until you hear or feel a click. Verify that the strap is secure before wearing the watch.

Yes, any strap with an 18-millimetre lug width is compatible with the Tissot PR 100 T101.910.11.121.00, regardless of the manufacturer. Quality aftermarket straps, such as those offered by MilanoStraps, guarantee perfect fit and often exceed the construction standards of OEM straps. It is important to verify that the strap has been manufactured for exactly 18mm, not approximate dimensions, to avoid fitting problems.

The lifespan of a leather strap depends on the quality of the material, frequency of use, and environmental conditions. An alligator or shell cordovan strap with vegetable tanning, worn daily, typically lasts 3-5 years before replacement becomes necessary due to natural wear. Softer calf leather straps may last 2-3 years with similar usage. Proper maintenance—avoiding prolonged exposure to water, perspiration, and direct UV rays—significantly extends the strap's life. MilanoStraps offers straps engineered for durability, with stitching and materials selected to age with distinction.
