Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1200-1233?

The lug width of the Endeavour 1200-1233 is 20mm, measured between the case lugs. This specification is critical for strap compatibility. Milano Straps provides a fully tested collection of 20mm straps engineered for this model.

What strap is most suitable for the H. Moser & Cie Endeavour 1200-1233?

We recommend alligator or vegetable-tanned leather straps in dark tones (black, brown, cognac) for the 1200-1233. These materials complement the white gold case and smoked dial. NATO nylon straps in technical grades offer versatility. Avoid highly polished finishes that would conflict with the sober aesthetic of the watch.

How do I change the strap on my H. Moser & Cie Endeavour 1200-1233?

The spring bars on the Endeavour 1200-1233 are removable. Use a spring bar tool to gently prise the bar between lug and case without forcing. The bars are solid white gold and must not be damaged. We recommend working on a flat surface or consulting an authorised service centre if uncertain.

Can I use a third-party aftermarket strap on the H. Moser & Cie Endeavour 1200-1233?

Yes, provided the strap is certified 20mm lug width. Milano Straps supplies quality-verified aftermarket straps that ensure proper fit without lateral play. Avoid low-grade straps that could damage the gold lugs through friction or oxidation over time.

What is the lifespan of a leather strap on the 1200-1233?

A high-quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years with regular wear. Longevity depends on frequency of use, moisture exposure, and care. A visibly cracked or weakened strap should be replaced to avoid sudden failure. NATO and rubber straps typically last 5–8 years.
