Lug width
Frequently asked questions
What is the lug width of the Tissot PR 100 T101.010.33.451.00?
The lug width of the Tissot PR 100 T101.010.33.451.00 is 12 millimetres. This measurement determines compatibility with any aftermarket strap and represents the space between the case lugs (horns). Precise measurement requires removal of the original strap and measuring the internal distance between the attachment pins—an operation anyone can perform with a calliper or millimetre ruler.
Which type of strap is best suited for the Tissot PR 100 T101.010.33.451.00?
For the 25mm PR 100, we recommend three options based on use case. For formal wear: calf leather with vegetable tanning or shell cordovan, which develop natural patina over time. For daily and sports use: NATO straps in ballistic nylon fabric, offering practicality and quick rotation. For humid or aquatic environments: FKM rubber (Viton), which resists moisture and saltwater exposure. We advise against synthetic materials, which degrade rapidly.
How do I change the strap on my Tissot PR 100 T101.010.33.451.00?
Strap replacement involves removing the spring bars connecting the strap to the case lugs. Use a dedicated spring bar tool or a small flathead screwdriver to press one bar laterally until its internal spring yields. Extract the bar and remove the worn strap. Align the new strap's holes with the lugs and reinsert the bar. Verify it clicks fully into position. The operation takes 2-3 minutes for experienced users, 5-10 minutes for beginners.
Can I use an aftermarket compatible strap on my Tissot PR 100 T101.010.33.451.00?
Yes, any strap with a 12-millimetre lug width is compatible with the T101.010.33.451.00. Quality aftermarket straps offer significant advantages: wider colour and material variety (alligator, shell cordovan, technical NATO), customisation options, and often superior longevity compared to originals. Always verify the lug width is exactly 12mm and that the attachment slots align perfectly before installation.
How long does a leather strap last on a Tissot PR 100 T101.010.33.451.00?
Leather strap durability depends on quality and usage patterns. Quality vegetable-tanned hides (calf, alligator, shell cordovan) maintain structural integrity for 5-8 years with moderate wear (3-4 days weekly). Synthetic leathers deteriorate within 12-18 months. Factors accelerating wear: direct intense sunlight exposure, acidic perspiration not dried promptly, persistent humidity without ventilation. A well-maintained leather strap—dried after perspiration, protected from direct light, occasionally treated with natural wax—can last over 10 years and develop desirable patina.
