The Hampton 10027 (aka: MOA10027, M0A10027), seen from the bench

The Baume & Mercier Hampton (reference 10027) is a contemporary reinterpretation of 1930s Art Déco design featuring a 32.30 mm stainless steel case with a domed sapphire crystal. It houses the Swiss ETA 2895-2 caliber, displaying hours, minutes, small seconds, and date. The 18 mm lug width accommodates refined leather straps such as dark alligator or burgundy shell cordovan, while the satin finish case offers 30 meters water resistance for daily elegance.

Frequently asked questions

What is the lug width of the Baume & Mercier Hampton 10027?

The lug width of the Baume & Mercier Hampton 10027 is 18 millimetres. This measurement is determined by the rectangular case geometry and the lugs welded to the case body. To verify strap compatibility, use a digital calliper to measure the lug width at the point where the lug meets the case, keeping the calliper arms parallel.

Which strap is most suitable for the Baume & Mercier Hampton 10027?

For the 10027, we recommend a dark brown alligator or red mahogany shell cordovan, which create elegant contrast with the steel case and respect the Art Deco aesthetic. If you prefer a lighter leather, vegetable-tanned veal offers sophistication and ages beautifully. For casual daily wear, an anthracite grey cotton Jacquard NATO provides practicality whilst maintaining stylistic coherence.

How do I change the strap on my Baume & Mercier Hampton 10027?

To change the strap on your 10027, proceed as follows: remove the deployant clasp from the old strap by pressing the side buttons; release the lug springs by inserting a thin tool into the slots on either side of the case; remove the strap from the first lug, then the second; insert the new strap into the lugs, ensuring the springs click into position; reattach the deployant. If unsure, consult a trusted watchmaker.

Is an aftermarket strap compatible with the Baume & Mercier Hampton 10027?

Yes, any strap with 18mm lug width is compatible with the 10027. You can choose from standard straps available online, ready to ship, or commission bespoke straps from the Casati Milano atelier, which guarantees personal leather selection, customisation (initials, stitching thread) and an 18-month warranty.

How long does a leather strap last on the Baume & Mercier Hampton 10027?

Longevity depends on material and use. A quality alligator or shell cordovan, with regular care (brushing, moisture protection), maintains structural integrity for 5–7 years of daily wear. Vegetable-tanned veal offers 3–4 years under normal conditions. Leather wears naturally at the lugs and pass-through point, where the strap experiences mechanical stress. A uniform dark patina indicates natural ageing; fine creasing is an aesthetic characteristic. Replace the strap when leather separates from the lugs or when the pass-through deteriorates.

The next step

The right strap isn't chosen. It is built, together.
