The Diver ARAAFBLR1BU1, seen from the bench

The Bausele Diver ARAAFBLR1BU1 is an Australian contemporary interpretation of the diving watch, combining toolwatch heritage with essential, purposeful design. This 42mm stainless steel diver features a Sellita SW200-1 automatic movement offering ±10 seconds monthly precision and 38 hours power reserve. The 316L steel case resists saltwater corrosion effectively, while the readable dial and luminous indices ensure visibility at depth. The 22mm lug width requires proper measurement for compatible aftermarket straps.

Frequently asked questions

What is the lug width of the Bausele Diver ARAAFBLR1BU1?

The lug width of the Bausele Diver ARAAFBLR1BU1 is 22mm. This measurement represents the distance between the two lateral lugs of the case where the strap is attached. To verify compatibility with an aftermarket strap, measure this distance using a digital calliper: 22mm straps will fit correctly, ensuring both aesthetic and functional solidity.

Which strap pairs best with the Bausele Diver ARAAFBLR1BU1?

The ideal strap for the Bausele Diver ARAAFBLR1BU1 depends on your intended use. If you dive regularly, a navy or black NATO in technical fabric resists moisture and dries quickly. If you alternate occasional immersions with terrestrial daily wear, brown or tobacco alligator delivers versatile elegance. For purely aquatic environments, vulcanised rubber ensures optimal grip and maximum practicality.

How do I change the strap on the Bausele Diver ARAAFBLR1BU1?

To change the strap on the ARAAFBLR1BU1, obtain a spring bar tool or consult a specialist craftsman. Place the watch on a stable surface, locate the two lateral pins securing the strap to the lugs, gently compress them with the tool to release tension, then remove the old strap. Align the new strap's holes with the pins, reinsert the pins until they click into place, verifying that both sides are firmly secured.

Are 22mm aftermarket straps compatible with the Bausele Diver ARAAFBLR1BU1?

Yes, any 22mm strap is compatible with the Bausele Diver ARAAFBLR1BU1, provided the spring bars meet standard diameter and thickness specifications. We recommend straps of elevated craftsmanship: vegetable-tanned alligator, naturally tanned calf, NATO in regenerated fabric, or hand-vulcanised rubber. Always verify that the spring bars are stainless steel to prevent corrosion over time.

How long does a leather strap last on the Bausele Diver ARAAFBLR1BU1?

Leather strap longevity on the ARAAFBLR1BU1 varies according to material quality and usage patterns. Premium vegetable-tanned alligator typically lasts 3-4 years with daily wear; naturally tanned calf 2-3 years. Regular water exposure accelerates degradation: if you frequently submerge the diver, a leather strap lasts approximately 18-24 months. To extend lifespan, apply a protective layer of colourless wax every 3-6 months and store the strap in a dry environment when not worn.
