Strap for PR 100 Powermatic 80 39 Stainless Steel / Blue / Bracelet

The lug width of the Tissot PR 100 T101.407.11.041.00 is 10mm. This measurement is specific to the model and ensures balanced proportions between case and strap. It is essential to measure precisely the internal space between the lugs before purchasing an aftermarket strap to avoid misalignment or structural play.

For the Tissot PR 100 T101.407.11.041.00, we recommend alligator for formal contexts, vegetable-tanned calf leather for versatile elegance with noble ageing, and NATO or rubber for technical and sporty use. The choice depends on intended use and dial colour: light dials pair with dark colours (burgundy, brown), while dark dials suit honey or cognac tones.

To change the strap, obtain a precision spring bar tool. Position the watch with the strap facing downward, gently insert the tool into the slot beneath the lug, press to compress the internal spring pin, and slide the lug out of its housing. Repeat on the other side. Insert the new strap by aligning the holes with the lugs and pushing until the pin clicks into position. Always work on a soft surface to prevent scratches.

Any strap manufactured with a 10mm lug width is compatible. Milano Straps offers a certified selection of alligator, calf, leather NATO, and rubber constructed to this exact measurement, with precision tolerances ensuring perfect fit without stress on the case. Avoid approximate-width straps (9.5mm or 11mm) that damage both case and strap.

A high-quality alligator or calf leather strap, worn regularly, lasts 3-5 years. Factors influencing longevity: frequency of wear, humidity exposure, stitching quality, and tanning method. Vegetable tanning develops patina over time while maintaining elasticity. A NATO or rubber strap resists 4-7 years due to absence of fragile natural fibres. Regular maintenance with specific cleaner significantly extends lifespan.
