Frequently asked questions

What is the exact lug width of the Elka Watch Co. D-Series D06-0901?

The D06-0901 features a lug width of 20 mm. This measurement is precise and does not tolerate variation: compatible straps must be constructed with lugs machined to exactly 20 mm external width, respecting constructive tolerances and the pitch of the case lug design.

Which strap is best suited to the Elka D06-0901?

The D06-0901 pairs ideally with straps in vegetable-tanned alligator, shell cordovan, or grained calf leather. For a sporty aesthetic, structured-fabric NATO straps or FKM rubber straps are recommended. Your choice depends on use case: formal for alligator, versatile for NATO, refined for cordovan.

How do you change the strap on an Elka Watch Co. D-Series?

The strap is changed using a spring bar removal tool. Gently extract the pins securing the strap to the case lugs, taking care not to lose the small springs. Once removed, insert the new strap and secure it with the pins, ensuring they are firmly seated. If inexperienced, we recommend consulting a professional watchmaker.

Can I use an aftermarket strap on this model?

Yes, you can use aftermarket straps compatible with a 20 mm lug width. However, constructive quality is essential: the lugs must be machined with precision, the pins must move smoothly, and the strap must present no imperfections at contact points. Low-quality straps can compromise the wearing experience of the D06-0901.

How long does a leather strap last on an Elka D06-0901?

The lifespan of a leather strap depends on tanning method, usage, and maintenance. A quality alligator or shell cordovan strap can last 5-8 years with ordinary care. Grained calf, being more delicate, typically lasts 3-5 years. The natural patina that develops is part of leather's beauty but also evidence of ageing. Regular maintenance extends strap life.
