Strap for WW1 Argentium Silver

The lug width of the Bell & Ross Vintage BRWW1-ME-AG-SI/SCR is 20 millimetres. This measurement represents the distance between the two lugs (metal axes) on which the strap rests. To verify it, use a digital calliper to measure the usable distance between the lugs without including the case shoulders.

For the BRWW1-ME-AG-SI/SCR, we recommend an alligator or shell cordovan strap in vegetable tanning, which enhance the classical-sporty aesthetic of the model. Alternatively, a grained calf leather with a steel deployante clasp offers daily comfort, whilst a military NATO strap emphasises its instrumental heritage. For aquatic use, FKM rubber ensures complete reliability.

Obtain a spring bar tool (an inexpensive tool costing only a few pounds). Position your watch with the lugs facing towards you, position the tip of the spring bar tool into the small hole of the lug, apply gentle pressure and push it downwards until the pin emerges. Repeat on the other side. Insert the new strap by aligning the holes with the pins, then reinsert the pins from both sides until you hear a click of engagement.

Yes, any strap with a 20-millimetre lug width is compatible. We recommend artisanal quality leathers, such as alligator, shell cordovan, grained calf or NATO in ballistic nylon. Always verify that the spring bars are of the correct diameter (typically 1.5 or 1.8 mm) for secure attachment.

A quality leather strap with vegetable tanning and artisanal finishing lasts an average of 3-5 years with daily wear, developing a beautiful patina over time. Shell cordovan and alligator can last well beyond 5 years. Durability depends on sun exposure, humidity and frequency of wear. Casati Milano offers an 18-month warranty on all straps produced in the atelier.
