Strap for Alter Ego Stainless Steel / Black / Bracelet

The TAG Heuer Alter Ego WP1310.BA0750 has a lug width of 20mm. This measurement represents the distance between the pins that anchor the strap to the watch case lugs. It is a precise dimension and essential for compatibility: any strap purchased must be calibrated exactly to 20mm to ensure a perfect fit without play or forcing.

The best strap depends on intended use and personal preferences. For classical and elegant wear, alligator is the most noble choice: the natural grain and suppleness create a captivating contrast with the steel case, whilst developing a unique patina over time. For those preferring everyday versatility, vegetable-tanned calf offers superior resistance and a satin finish. For sports contexts, rubber or canvas straps maintain the technical DNA of the model.

To change the strap, you must remove the pins that secure it to the case lugs. Using a specialized tool (a small lever or dedicated remover), push the pin inward from the opposite side of the lug until it comes out completely. Once removed, the old strap can be slid off. The new strap is threaded through the lugs, aligning the holes, then the pins are reinserted and pushed until properly seated. Care should be taken to avoid scratching the case during the operation.

Yes, absolutely. Any quality artisanal strap with a 20mm lug width is compatible with the WP1310.BA0750. Aftermarket straps offer the opportunity to personalise the watch with noble materials (alligator, shell cordovan, anilina calf) and finishes that often exceed the quality of the original bracelet. Milano Straps offers straps certified for this reference, available online and customisable at the Casati Milano atelier.

Durability depends on leather quality and usage patterns. An alligator or premium calf strap, worn daily, can last 4–6 years before requiring maintenance or replacement. Vegetable-tanned leather tends to be more resilient, developing a protective patina over time. Prolonged exposure to moisture and heat reduces lifespan. With regular maintenance (gentle cleaning, proper drying, occasional conditioning), durability can be extended significantly. Artisanal straps from Milano Straps include an 18-month warranty.
