Strap for PR 100 Chronograph Quartz 38 Stainless Steel / Silver / Bracelet

The lug width (distance between the lugs) of the Tissot PR 100 T049.417.11.037.00 is 20 millimetres. This parameter is the determining factor for mechanical compatibility with any aftermarket strap. Always measure the lug width perpendicularly to the case using a ruler or calliper to ensure accurate measurement.

The choice depends on intended use: for formal and business environments, an alligator strap is recommended, as it dialogues elegantly with the brushed steel case. For mixed use and weekends, Italian calfskin offers versatility and superior durability. For sporting and casual scenarios, NATO straps in ballistic nylon or silicone rubber models radically transform the timepiece's aesthetic towards a more contemporary and practical character.

The procedure requires removal of the spring bars (shoulder pins) that connect the strap to the lugs. Use a dedicated spring bar tool to compress the pin laterally, freeing the end. Remove the old strap and insert the new one by aligning the lugs with the pin's mounting holes. The procedure requires precision to avoid damage to the case or pins.

Yes, any strap with a 20mm lug width is mechanically compatible.

The sartorial consultation of the Casati Milano atelier ensures aesthetic and constructive pairings appropriate to your timepiece.

A quality leather strap constructed from vegetable-tanned leather generally lasts between 2 and 4 years under daily-use conditions, developing a characteristic and predictable patina. Durability depends on frequency of use, exposure to moisture and perspiration, and proper maintenance (periodic cleaning and conditioning). Italian calfskin straps compete favourably with historic Swiss brands, offering superior longevity compared to lower-tier leathers.
