Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1200-1213?

The Endeavour 1200-1213 features a 20mm lug width. This measurement, taken between the inner terminals of the case, ensures proper proportions with the 40mm case diameter. To verify, position a ruler against the lugs where the original strap attaches to the case.

What is the best strap for the Endeavour 1200-1213?

The ideal strap depends on intended use. For classical elegance, we recommend alligator with vegetable tanning or dark shell cordovan, which create harmonic tonality with the fumé dial. For daily versatility, a fine-grained calf or cotton-wool NATO maintains Moser's minimalist philosophy. For sports wear, a satin-finish FKM rubber strap offers practicality without aesthetic compromise.

How do you change a strap on a watch with 20mm lugs?

To change the strap, remove the watch from your wrist and locate the spring bars connecting the strap to the case lugs. Using a spring bar tool, gently press the bar toward the case centre to release it from its seat, then withdraw the strap. Insert the new strap by aligning the holes with the anchor seats and release the bar, allowing it to snap into position. Verify stability before wearing.

Is a 20mm aftermarket strap truly compatible with the 1200-1213?

Yes, provided it is specifically manufactured for 20mm lug width and the lugs are designed for Endeavour case geometry. Premium artisanal straps, such as those in alligator or shell cordovan, offer superior fit tolerance compared to industrial standard products. Always verify there are no gaps between strap and case once mounted.

How long does a leather strap last on a daily-worn watch?

Strap longevity depends on tanning type, leather quality, and intensity of use. A shell cordovan or vegetable-tanned alligator strap, worn daily, has an average lifespan of 4-7 years before replacement due to natural fibre wear. Fine-grained calf typically lasts 2-4 years. Exposure to moisture, heat, and perspiration accelerates ageing; regular maintenance (gentle cleaning and hydrophobic treatments) extends longevity.
