PRS 516 T91.1.488.41— lug 20mm

The lug width of the Tissot PRS 516 T91.1.488.41 is 20 millimetres. This dimension represents the free width between the two lugs of the case and is fundamental for strap compatibility. To measure correctly, position the watch horizontally and use a digital calliper perpendicular to the lugs, recording the internal distance. An incorrect measurement results in incompatible straps that either protrude laterally or leave empty spaces.

The best strap for the PRS 516 T91.1.488.41 depends on usage and aesthetic preference. For an elegant approach, choose a black or brown alligator leather in vegetable tanning, which amplifies the chronograph's racing austerity. A grained calf leather in tobacco or bordeaux creates refined contrast. For everyday versatility, a ballistic nylon NATO in dark grey offers practicality and rapid interchangeability. A vulcanised rubber with waffle texture is ideal for sports and outdoor contexts. All these materials are available in 20mm on Milano Straps.

To change the strap on the T91.1.488.41, remove the pins (or spring bars) connecting the strap to the lugs using a dedicated pin remover tool. Carefully extract the pin from the top, completely remove the first strap end, then proceed with the second. Insert the new strap by positioning one end first, then the other. Use the pin remover to reinsert the pins, ensuring they are fully secured. If inexperienced, entrust the operation to a qualified watchmaker to avoid damage to the lugs.

The Tissot PRS 516 T91.1.488.41 accepts straps from any brand with a 20mm lug width, provided the width matches exactly. On Milano Straps you will find handcrafted straps in alligator, shell cordovan, calf, NATO and rubber, all produced to superior quality standards. Always verify that the strap has the same fixing systems (pins or spring bars) as the original model to ensure mechanical compatibility beyond dimensional compatibility.

The lifespan of a leather strap depends on usage, material quality and maintenance. An alligator or shell cordovan strap with vegetable tanning, worn regularly but not daily (4-5 days per week), typically lasts 3-5 years. Constant exposure to moisture, sweat and sunlight accelerates ageing. A medium-quality calf leather has a slightly shorter lifespan (2-3 years of intensive use). To extend longevity, apply natural balms every 6 months, avoid prolonged immersion and store the watch in dry environments. NATO and rubber straps are virtually indestructible, requiring only periodic cleaning.
