Strap for Classima Executives Quartz

The Baume & Mercier Classima 10131 features an 18-millimetre lug width, a classic dimension that characterises elegant wristwatches of medium proportions. This measurement allows you to select from a wide range of leather and fabric straps, whilst maintaining the visual balance of the 39mm case.

We recommend considering alligator leather for a formal aesthetic, as its natural texture reflects the watch's discreet character. For daily wear, vegetable-tanned calf leather ensures graceful ageing and patina development. For more casual contexts, NATO straps in fabric or rubber models with subtle grain offer versatile styling options that complement the Classima's profile.

The Classima 10131 requires careful handling: use specialised tools such as springbar removers to extract the suspension pins without damaging the case. If you lack experience, the Casati Milano atelier provides professional replacement services with expert guidance on measurements and finishes, ensuring perfect aesthetic harmony between timepiece and strap.

Yes, any strap with an 18-millimetre width is mechanically compatible. However, we recommend selecting your strap with particular care regarding thickness, colour and texture to preserve the Classima's sober elegance. Our straps are specifically designed for watches in this category, with attention to proportionate pairings and harmonious finishes.

A quality leather strap, maintained with regular care such as cleaning and moisture protection, typically lasts 3 to 4 years if worn daily, or longer if rotated with other straps. Vegetable-tanned leather ages beautifully, developing character and patina. Our straps include an 18-month warranty against manufacturing defects.
