Strap for Rolex Oyster Perpetual 6494

The Rolex Oyster Perpetual 6494 has a lug width of 20 mm, measured internally between the lugs using a digital calliper. The standard buckle width is 16 mm. All 20mm-compatible straps on milanostraps.it are designed to fit this geometry without forcing.

For the 6494, a vegetable-tanned alligator strap is the most coherent choice given the watch's vintage aesthetic, developing a patina over time that complements the ageing of original components. Alternatively, a domed calf leather strap in tobacco tones or a two-colour NATO nylon strap offer respectively elegant and sporting interpretations, both historically appropriate for a 1950s Oyster.

To replace the strap on the 6494, use a fine-tipped spring bar tool (flat or forked tip) to remove the spring bars from the lugs. Work on a soft surface to avoid scratching the case. Original spring bars have a diameter of 1.8 mm and a length of 20–21 mm; they can be reused if in good condition, or replaced with equivalent quality aftermarket bars.

Yes. Any strap with a 20 mm lug width and a straight or slightly curved end is compatible with the 6494. Milano Straps offers handcrafted leather, NATO, and rubber straps specifically selected for 20mm lug width, with finishes and materials consistent with the vintage Oyster aesthetic.

Longevity depends on material and usage: a quality vegetable-tanned alligator strap, with regular care (conditioning with specific leather cream, rotation between multiple straps), can last 3 to 7 years before requiring replacement. Shell cordovan tends to last even longer due to the density of the fibre. Daily use in humid or sporting environments significantly reduces leather life; in such contexts, a vulcanised rubber strap is recommended.
