Strap for Alter Ego Stainless Steel - Diamond / MOP / Bracelet

The lug width of the TAG Heuer Alter Ego WP1317.BA0751 is 20mm. This dimension was carefully calculated by TAG Heuer to maintain proportional harmony between the compact 29mm case and the wearer's wrist. Always verify your watch's lug width by measuring the internal distance between the lugs directly on the case.

The best strap depends on intended use and personal preference. For formal elegance, we recommend alligator in black or cognac, which emphasizes the case's geometric minimalism. For daily versatility, vegetable-tanned calf leather offers durability and develops a natural patina over time. Avoid overly thick straps or vibrant colours: the Alter Ego demands materials that respect its minimalist identity.

To change the strap on the WP1317.BA0751, you will need a spring bar tool. Position the watch horizontally, insert the tool into the lateral opening of the lug, lift gently until the spring releases, then slide the old strap upward. Repeat for both sides. Install the new strap by aligning the lugs into the corresponding holes and pressing until you hear a click.

Yes, all straps with a 20mm lug width are compatible with the WP1317.BA0751. Milano Straps offers a curated selection of artisanal 20mm straps customizable by colour, initials, and stitching thread.

A high-quality leather strap typically lasts 3-5 years with regular but not extreme use. Longevity depends on the tanning method used (vegetable-tanned leather outlasts chrome-tanned), sunlight and humidity exposure, and frequency of wear. Vegetable-tanned leather straps develop a compelling patina and can last considerably longer if properly maintained. Milano Straps offers straps with an 18-month guarantee.
