Strap for Clifton Baumatic Stainless Steel / Black / Alligator

The Baume & Mercier Clifton 10399 has a lug width of 20 millimetres. This dimension is standardised across the model and allows you to use any strap compatible with this width, ensuring a precise fit without the need for adapters.

The best strap depends on your intended use and personal preferences. For formal occasions, a cognac alligator or polished black alligator complements the two-tone case beautifully. For everyday wear, a vegetable-tanned calf strap or a rubber strap offers comfort and durability. Aged shell cordovan is ideal if you wish for a historical patina that develops character over time.

The Clifton 10399 is fitted with spring bars located on the case flanks. To remove the strap, apply gentle inward pressure to the spring bar using a pointed tool (such as a spring bar tool), release the mechanism, and extract the bar. To install a new strap, insert the spring bar into the new strap's attachments and snap both ends of the bars into the case holes.

Yes, all straps with a 20mm lug width are compatible with the Clifton 10399. Milano Straps offers a selection of high-quality aftermarket straps in alligator, calf, shell cordovan, and rubber, customisable in size, initials, and thread colour. For more specific requirements, the Casati Milano atelier handcrafts bespoke straps with personal selection of hides and an 18-month warranty.

The durability of a leather strap depends on the material and usage. A high-quality alligator or aged shell cordovan strap, subject to periodic maintenance (gentle cleaning and storage in a dry environment), can last 5–8 years or longer. A vegetable-tanned calf strap has an average lifespan of 3–5 years. Rotating between multiple straps extends the life of each by allowing the leather to dry naturally between uses.
