Strap for PRS 200 Quartz Chronograph Silver Eyes

The lug width of the Tissot PRS 200 T17.1.486.53 is precisely 19.00mm. This dimension is determined by the internal geometry of the case and corresponds to the internal diameter between the spring bar pins. Tissot's manufacturing tolerance falls within ±0.2mm, making straps certified for 19mm fully compatible. Avoid 18mm or 20mm straps, which would cause excessive play or insertion difficulties.

The Tissot PRS 200 accommodates 19mm straps in alligator, calf, NATO, and rubber. For a more formal appearance, choose vegetable-tanned alligator in warm tones. For daily sports wear, brushed calf or ballistic nylon NATO straps offer robustness and versatility. For humid environments or intensive use, vulcanised rubber ensures greater durability without accelerated deterioration.

Strap replacement requires extraction of the spring bars from the pins located on the case lugs. Use a dedicated spring bar tool, inserting it gently between the lug and existing strap to compress the spring and release the pin. Once extracted, remove the old strap and insert the new one, aligning the holes. Compress the spring again while inserting the pin into the lug. The operation requires moderate pressure and care to avoid scratching the case.

Yes, the market offers numerous aftermarket straps certified for 19mm lug width. Selecting manufacturers with proven expertise in producing straps for Swiss watch brands ensures precise tolerances and materials consistent with original manufacturing standards. Avoid generic straps from suppliers without specialisation, which may present critical dimensional deviations. Always verify compatibility with lug width before purchase.

Durability depends on material, frequency of use, and environment. An alligator or shell cordovan strap with vegetable tanning typically lasts 3-5 years with moderate daily use, developing a beautiful patina over time. Brushed calf resists for 2-4 years before showing wear signs. Heavy canvas NATO straps easily surpass 5-7 years. Vulcanised rubber maintains structural integrity for 4-6 years even in extreme conditions. Extending strap life requires rotation amongst multiple pieces and protection from excessive moisture during storage.
