Frequently asked questions

What is the lug width of the Bausele Diver BESSSM1OR1?

The Bausele Diver BESSSM1OR1 features a 22mm lug width, a standard measurement for contemporary dive watches. This width is compatible with our entire 22mm strap collection, from Tuscan leather to NATO and Japanese cordovan. Always verify your lug width using a calliper: position it perpendicular to the spring bars for accurate measurement.

Which leather strap pairs best with the Bausele Diver BESSSM1OR1?

To honour the functional ethos of the BESSSM1OR1, we recommend vegetable-tanned Tuscan leather straps, which develop a natural patina over time. Tuscan cognac is the balanced choice: its organic texture harmonises with the stainless steel case. If you seek more dramatic grain, Japanese shell cordovan offers a tight weave and profound colour development during aging.

How do I change the strap on the Bausele Diver BESSSM1OR1?

To change a strap on a 22mm lug width: 1) position the watch on a soft pad; 2) use a spring bar tool (available at specialist retailers) to gently push the bar inward, gripping the spring; 3) extract the bar from the lug seat; 4) repeat on the opposite lug. Insert the new strap by aligning the hole with the lug and press the bar until it clicks. Avoid excessive torque to prevent damaging the internal spring.

Are aftermarket 22mm straps compatible with the Bausele Diver BESSSM1OR1?

Yes. Any strap with a 22mm lug width is compatible with the BESSSM1OR1. Our 22mm strap collection has been tested on dive watches of identical lug width. Verify that total length (bracelet side + wrist side) is proportionate to your wrist: the strap should not appear excessively short or long relative to the 39.5mm case.

How long does a leather strap last on the BESSSM1OR1?

A quality vegetable-tanned Tuscan leather strap offers an average lifespan of 3–5 years of daily wear, varying by frequency of use and environmental conditions (humidity, sun exposure, perspiration). Japanese shell cordovan typically lasts longer (5–7+ years) due to fibre density. Regular maintenance (cleaning with a damp cloth, annual conditioning with specific balm) significantly extends strap longevity.
