Baume & Mercier
Hampton 10030 (aka: MOA10030, M0A10030)— lug 18mm

The lug width of the Baume & Mercier Hampton 10030 is 18 millimetres. This measurement is taken perpendicular to the two lugs that secure the strap, not the distance between the spring bars. It is essential to verify this dimension before ordering an aftermarket strap.

For this model, alligator remains the most appropriate choice, reflecting the Art Déco spirit of the watch. Alternatively, shell cordovan or vegetable-tanned calf leather offer excellent aesthetic and tactile results. NATO straps or rubber are not recommended, as they do not enhance the formal elegance of the case.

Remove the two spring bars securing the strap using a dedicated spring bar tool. This procedure requires careful attention to avoid scratching the case. Insert the new 18mm strap through the lug holes and reinsert the spring bars with calibrated pressure. If you are inexperienced, we recommend consulting a professional to prevent damage.

Yes, any strap with an 18mm lug width is compatible. However, choose brands that guarantee constructive quality (saddle-stitched seams, precise finishing) to justify your investment in the watch. Milano Straps offers bespoke, personalizable straps for this width.

Durability depends on material and usage. High-quality alligator or shell cordovan lasts 3–5 years with daily wear, developing a beautiful patina over time. Vegetable-tanned calf tends to wear slightly faster (2–4 years) but acquires charming ageing characteristics. Proper periodic conditioning extends service life.
