Frequently asked questions

What is the lug width of the Bell & Ross High-Tech Space 1 M?

The Bell & Ross Space 1 M has a lug width of 22mm. This measurement is specific to the 44mm oversized case and is standard for large-diameter vintage-inspired chronographs. To verify compatibility, measure the inner distance between the lugs (lug-to-lug) or the width of the space where the original strap sits.

What is the best strap for the Bell & Ross Space 1 M?

The best strap depends on your intended use. For formal and professional applications, a dark brown or black alligator leather with vegetable tanning offers elegance and durability. For tactical or outdoor environments, a heavyweight cotton NATO strap provides quick-change capability and resilience. Shell Cordovan is ideal if you desire extraordinary durability and an evolving patina over time.

How do you change the strap on the Bell & Ross Space 1 M?

Strap replacement is performed via the lugs. Use a spring bar tool to gently extract the elastic bars (spring bars) that connect the strap to the case. Once freed, remove the old strap and insert the new one, aligning the lug holes with the corresponding slots on the case lugs. Ensure the spring bars are securely seated.

Can I use an aftermarket strap on this Bell & Ross model?

Yes, you can use any quality strap with a 22mm lug width. Aftermarket straps are fully compatible and offer greater stylistic and material choices than original options. Ensure the lug width is precisely 22mm and that the strap thickness accommodates the case's lug slots.

How long does a leather strap last on a watch like the Bell & Ross Space 1 M?

A quality leather strap with vegetable tanning or alligator leather typically lasts 3–5 years under normal wear conditions (daily use with breaks). Durability depends on humidity, sun exposure, frequency of use, and maintenance applied. Shell Cordovan straps last longer, up to 7–10 years. Regular maintenance (cleaning, drying, conditioning) significantly extends service life.
