Strap for Tangente 38 Datum

The Tangente 130 features 18 mm lugs, a rare dimension in contemporary watchmaking. Measurement is taken internally between the upper and lower attachment points of the case. This size maintains rigorous proportions with the 37.50 mm diameter and requires bespoke strap construction rather than universal options.

Alligator with vegetable tanning is the reference choice: the pronounced grain and natural patina development over time enhance the watch's German character. An equally sophisticated alternative is fine-textured calf, whilst cotton-polyester NATO maintains Bauhaus rigour. FKM rubber is a practical choice for informal daily wear, though less expressive of the Tangente's minimalist essence.

The Tangente 130's lugs are removed using a spring bar tool or small flat screwdriver. Position the tool in the lateral lug hole, compress the internal spring, extract the current lug and insert the new one. The operation is straightforward but requires precision to avoid case scratching. Casati Milano offers professional strap changes by appointment.

Yes. The 18 mm lug width of the Tangente 130 is served by specialist bespoke strap manufacturers such as milanostraps.it. Aftermarket straps in alligator, calf and rubber are built to measure, ensuring precise mechanical compatibility and construction quality superior to generic market alternatives.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years with daily wear, accounting for natural leather ageing and flex-point wear. Longevity depends on intensity of use, climatic conditions and maintenance. Protection from excessive perspiration and humidity significantly extends strap lifespan.
