Frequently asked questions

What is the lug width of the Bausele Diver BESSSM1WH1?

The lug width of the Bausele Diver BESSSM1WH1 is 22mm. This dimension is measured between the inner edges of the two spring bar pins that attach the strap to the case. It is essential to verify this measurement with a digital calliper before purchasing an aftermarket strap, as even minor measurement errors will compromise compatibility.

Which strap do you recommend for the Bausele Diver BESSSM1WH1?

For the BESSSM1WH1 we recommend straps in vegetable-tanned Italian calf (ocean blue or cognac brown for chromatic harmony), alligator for a dress-watch approach, or FKM rubber for frequent underwater use. Vegetable-tanned calf offers natural ageing and progressive patina development; rubber guarantees UV resistance and pool use without compromise.

How do I change the strap on the Bausele Diver BESSSM1WH1?

The process is straightforward: position the watch on a soft support, use a spring bar remover tool or small screwdriver to push the pin laterally from one side. The pin will slide out. Repeat on the other side. Insert the new strap by aligning the holes with the pins, then press the pin in from both sides until it clicks into position. Verify that the strap is centred relative to the case.

Is a 22mm aftermarket strap compatible with the Bausele Diver BESSSM1WH1?

Yes, provided the strap has an exact lug width of 22mm and the pins use the same diameter (typically 1.8mm for watches in this class). All our 22mm straps are tested and compatible with the BESSSM1WH1. We recommend verifying the technical specifications on the product sheet before purchase.

How long does a leather strap last on the Bausele Diver BESSSM1WH1?

A vegetable-tanned Italian calf strap on a dive watch such as the BESSSM1WH1 typically lasts 18–36 months with daily wear and protection from direct moisture and prolonged chlorine contact. Frequent exposure to salt water or humid environments accelerates wear. FKM rubber, conversely, resists indefinitely. Regular maintenance with appropriate creams extends the useful life of the leather strap.
