Strap for Aquaracer 300M Quartz 40.5 Stainless Steel / Yellow Gold / Silver / Bracelet

The lug width is 20mm. This measurement corresponds to the distance between the case lugs where the bracelet or strap is attached. To measure accurately, use a digital calliper and measure the width of the space between the two mounting pins: it must be exactly 20mm.

There is no universal choice, but it depends on usage: dark brown alligator offers timeless and formal elegance; shell cordovan develops a rich and sophisticated patina over time; vegetable-tanned calfskin ensures comfort and a more casual appearance; black or navy blue rubber maintains the original sporty character. The two-tone case in gold and steel pairs beautifully with all these options, so the choice is dictated by context of use.

Insert a spring bar tool into the tiny hole between the case lug and the spring ring. Press gently inward to compress the spring and extract the pin. Repeat from the other side. Once the bracelet is removed, insert the new strap: align the side holes of the strap with the pins and press until you hear a click. Make sure the strap is secure before wearing the watch.

Yes, any strap with a 20mm lug width is compatible. However, to achieve the best aesthetic and construction result, choose high-quality straps made with noble leathers and reliable stitching. Custom-made artisanal straps offer superior comfort and durability compared to standardised models.

A high-quality leather strap subjected to moderate use (worn 4-5 days per week) typically lasts 2-3 years before requiring replacement. Durability depends on intensity of use, ambient humidity and care: avoid prolonged contact with fresh and salt water (cover the strap when swimming), apply a protective balm every 6 months and store the watch in a dry environment. Shell cordovan and alligator age better than standard calfskin, developing a fascinating patina over time.
