The PR 100 T049.307.22.031.00 (aka: T0493072203100), seen from the bench

The Tissot PR 100 T049.307.22.031.00 is a refined interpretation of accessible Swiss watchmaking with a 27mm stainless steel case housing the reliable ETA caliber 2671 movement. The case features a protected crown, sapphire crystal, and 100m water resistance, while the sober dial displays applied indices and slender hands with no decorative excess. The 20mm lug width represents the ideal proportion for this case size, ensuring proper fit between the strap attachment and the feminine wrist without oversizing.

Frequently asked questions

What is the lug width of the Tissot PR 100 T049.307.22.031.00?

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Tissot PR 100 T049.307.22.031.00 is 20mm. This measurement is proportionate to the 27mm case diameter and represents the model's standard construction. Always verify this dimension by placing a calliper between the metal lugs before purchasing an aftermarket strap.

Which strap do you recommend for the Tissot PR 100 27mm?

The ideal strap depends on your intended use and aesthetic preference. For daily elegance, we recommend calf leather in <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> or <a href="/pages/termine-glossario/alligatore">alligator</a>. For practicality and versatility, a nylon NATO strap or FKM rubber ensures durability and easy replacement. All combinations maintain aesthetic balance thanks to the 20mm lug width.

How do I change the strap on the Tissot PR 100 T049.307.22.031.00?

Replacement is straightforward: use a spring bar removal tool and gently insert it into the lateral holes of the case where the strap attaches. Press slightly downward to release the pins, remove the worn strap and insert the new one, ensuring the pins click securely into position. If unsure, a professional watchmaker can complete the operation in minutes.

Are there aftermarket straps compatible with the PR 100 T049.307.22.031.00?

Yes, all straps with a <a href="/pages/termine-glossario/misura-ansa">20mm lug width</a> are compatible. Milano Straps offers a selection of leather, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a>, alligator, NATO and rubber straps specifically calibrated for this width. Always verify that the attachment thickness fits correctly with the Tissot pins, as some manufacturing tolerances may vary slightly.

How long does a leather strap last on a daily-wear wristwatch?

A quality leather strap, made from calf or deer hide with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a>, typically lasts 18-24 months of intense daily use. Longevity depends on ambient humidity, pH of the wearer's perspiration and maintenance. Periodic cleaning with a soft cloth and occasional exposure to dry air extends its lifespan. Alligator straps, thanks to their more structured fibre, often exceed 24 months. Rubber and NATO straps offer greater longevity, up to 36+ months.
