Strap for Endeavour Dual Time, Platinum, Ardoise Dial

The lug width of the 1346-0301 is 20 millimetres. This measurement represents the internal distance between the two attachment pins of the case. It is essential to verify this dimension using a digital calliper before purchasing an aftermarket strap, as even minor deviations (18.5mm, 21mm) render the strap incompatible. The 20mm proportion has been calibrated by Swiss design to maintain aesthetic balance between the platinum case and the strap.

There is no universally 'best' strap, but rather the choice most coherent with your intended use and aesthetic sensibility. For the 1346-0301, we recommend three primary options: (1) alligator in black or dark brown with fine grain—creates a restrained contrast with the platinum and allows the fumé dial to remain protagonist; (2) vegetable-tanned calf—soft on the wrist, ages beautifully and develops a patina synchronised with the watch; (3) shell cordovan in burgundy—introduces three-dimensional depth that enhances the fumé tonality. Avoid synthetic leather or materials that betray the minimalist philosophy of the Manufacture.

Strap replacement requires a quality spring bar tool or dedicated watchmaker's instrument. Procedure: (1) position the watch on a soft, stable surface, case facing upward; (2) use the spring bar tool to gently compress the small metal spring that holds the pin inside the lug; (3) extract the pin from the case and old strap; (4) insert the new strap ensuring its width is exactly 20mm; (5) reposition the pin in both case lugs until you hear or feel the 'click' indicating secure fastening. If you lack experience, we recommend having this operation performed by a qualified watchmaker, particularly on a platinum piece of this significance.

Any strap with a lug width of exactly 20 millimetres is compatible with the 1346-0301. Before purchasing, always verify in the product specifications that the dimension is precisely 20mm, not 19mm, 20.5mm, or other variants. Milano Straps offers a curated selection of 20mm straps in alligator, calf, NATO, and technical rubber, all designed to respect the proportions and aesthetic of high-grade watches such as the Endeavour. Avoid generic or inferior-quality straps: the 1346-0301 deserves craftsmanship that matches its construction standard.

Leather strap longevity depends on use conditions, material quality, and care. An artisanal alligator or vegetable-tanned calf strap can last 3 to 5 years of daily wear, even up to 7–8 years with attentive maintenance (rapid drying after humidity exposure, protection from prolonged direct sunlight). NATO straps in robust cotton exhibit superior durability—up to 10 years—because the textile is less vulnerable to cracking. Leather naturally develops patina and changes colour over time: this is natural ageing, not deterioration. When the strap begins to flake or shows significant structural cracks, replacement is advisable. Artisanal quality permits minor repairs by a specialised craftsman.
