Crafted in 18-carat rose gold, this independent Swiss watchmaker's model exemplifies refined design without compromise.

Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1343-0102?

The lug width of the H. Moser & Cie Endeavour 1343-0102 is 20 millimetres. This measurement represents the distance between the two lugs that attach to the case and determines aftermarket strap compatibility. To verify the measurement correctly, position a ruler between the inner edges of the two lugs, ensuring you obtain a precise reading.

Which strap is recommended for the Endeavour 1343-0102?

For the H. Moser & Cie Endeavour 1343-0102 in rose gold, we recommend an alligator strap in cognac or bordeaux, which complements the warm tone of the rose gold beautifully. Alternatively, vegetable-tanned calf leather in dark shades (black, dark brown) ensures a natural patina that evolves over time. For a more casual interpretation, a grey charcoal NATO canvas maintains aesthetic coherence with the austere minimalism of the dial.

How do I change the strap on my H. Moser & Cie Endeavour 1343-0102?

To change the strap, you will need a spring bar tool. Place the watch on a soft surface, use the spring bar tool to compress the small internal spring of the pin, then extract the pin from the lug. Repeat on the opposite side. Insert the new strap by aligning the holes with the case lugs, reintroducing the pins. If you do not possess the specialist tool, we recommend consulting a certified watchmaker to avoid scratching the rose gold case.

Can I use an aftermarket strap compatible with my 1343-0102?

Yes, you can use a compatible aftermarket strap provided the lug width is precisely 20mm. Artisanal straps offer the opportunity to personalise the appearance of your Endeavour whilst maintaining aesthetic coherence with the rose gold case. Ensure that the strap features a deployante (folding clasp) if you desire wearing comfort and ease of adjustment, or opt for a traditional ardillon buckle for a more classical look.

How long does a leather strap last on a watch like the Endeavour 1343-0102?

The lifespan of a leather strap depends on usage intensity, climatic conditions, and material quality. A high-quality calf or alligator strap with vegetable tanning has an average lifespan of 4-6 years of moderate daily use. A standard calf strap might require replacement after 2-3 years if subject to intense wear. Prolonged exposure to moisture, direct heat, and perspiration accelerates ageing. The patina that forms naturally imparts character, but structural deterioration (cracks, fibre disintegration) necessitates replacement.
