Strap for Aquaracer 300M Quartz 27 Stainless Steel / Diamond / MOP - Diamond / Bracelet

The lug width is 20mm. This measurement is the standard for compact sports watches with a 27mm case and is determined by the internal distance between the attachment pins. Always verify compatibility by measuring with a digital calliper before purchasing an aftermarket strap.

We recommend a strap in natural alligator with vegetable tanning or Italian full-grain calf leather, which enhance the brushed stainless steel case. If you maintain active aquatic use, choose FKM rubber or NATO fabric resistant to water and chlorine. Your choice depends on lifestyle and frequency of water immersion.

Use a spring bar removal tool to extract the attachment pins from both sides of the case. Position the watch on a soft surface to prevent scratches. Insert the new strap ensuring the pin passes correctly through the lug hole, then close by pressing firmly until you feel the click. Verify the strap is symmetrical.

Yes, any strap with 20mm lug width is compatible. However, ensure the strap is artisanal quality and the spring bars are robustly constructed in stainless steel. Poor-quality straps can cause case scratches or pin failure during installation.

A high-quality natural leather strap lasts an average of 3-5 years with daily use, depending on care and exposure to moisture and UV. Vegetable-tanned leather tends to age better and develops an attractive patina. Avoid prolonged contact with water and chlorine, which accelerate wear. With proper maintenance (regular cleaning and conditioning), lifespan extends to 7-8 years.
