Strap for TT1 Chronograph Stainless Steel - Rubber / Black / Bracelet

The lug width is 24 mm, measured from the inside of one lug to the inside of the other where they meet the case. This measurement is the standard for Swiss sport chronographs in this category and ensures compatibility with all 24 mm artisanal straps.

The ideal strap depends on usage: vegetable-tanned calf leather enhances the technical character whilst adding elegance; a rubber strap maintains the sporty soul of the hybrid case; alligator leather transforms the chronograph for formal occasions. A cotton or ballistic nylon NATO offers versatility without compromise.

Use a dedicated strap removal tool to extract the spring bars (pins) that secure the strap to the lugs. Insert the tool into the notches on the side of the case, apply gentle pressure towards the centre to release the spring bar and remove the old strap. Align the holes of the new strap with the lugs and reinsert the spring bar with uniform pressure until it clicks into place.

Yes, provided the strap is certified for 24 mm lug width. Milano Straps offers artisanal straps specifically cut for this width, available in leather, alligator, rubber and NATO. Always verify that the lugs of the strap perfectly embrace the watch lugs with no play.

A quality leather strap, vegetable-tanned, typically lasts 3-5 years with moderate daily wear. Durability depends on exposure to sweat, moisture and sunlight. Patina and ageing marks are natural characteristics that increase aesthetic value over time.
