Frequently asked questions
What is the lug width of the Massena LAB Uni-Racer UR-001?
The Massena LAB Uni-Racer UR-001 features a 20-millimetre lug width. This measurement is taken between the case lugs and determines compatibility with all artisanal straps. A 20mm lug width is the industry standard that enables an extensive range of material choices, from vegetable-tanned leather to technical textiles and vulcanised rubber.
What is the best strap for the Uni-Racer UR-001?
Given the Massena LAB Uni-Racer UR-001's minimalist aesthetic, alligator straps with vegetable tanning magnify the case's formal clarity exceptionally well. Brown calf leather with natural patina is equally compelling for a warmer approach. For sport deployment, NATO straps in ballistic textile preserve the chronograph's understated elegance without functional compromise.
How do you change the strap on a 20mm lug width watch?
Strap replacement occurs via the spring bar—a small metallic component that pivots between the case lugs. Use a spring bar tool to depress the spring bar on one side, releasing tension. Once liberated, the spring bar slides away and the strap separates cleanly from the case. The operation is entirely reversible and requires no advanced technical expertise.
Can I use third-party compatible straps on the Massena LAB Uni-Racer UR-001?
Absolutely. The 20-millimetre lug width is an industrial standard ensuring compatibility with thousands of artisanal and industrially-produced straps. Aftermarket straps in vegetable leather, alligator, rubber, and textile are entirely compatible, provided they respect the 20mm width specification. The artisanal quality offered by Milan Straps provides alternatives superior to standard OEM offerings.
How long does a leather strap last on the Massena LAB Uni-Racer UR-001?
Leather strap longevity depends on tanning method and usage patterns. Quality vegetable-tanned calf leather typically endures 4-6 years of daily wear, developing a natural, compelling patina. Vegetable-tanned alligator is even more durable, easily achieving 8-10 years. Vulcanised rubber is essentially indestructible with ordinary maintenance. Periodic strap replacement is not inconvenience—it is an opportunity to curate and redefine your watch's visual identity.
