Frequently asked questions

What is the lug width of the Van der Gang Watches Gents 20004?

The lug width of the Van der Gang Watches Gents 20004 is 20mm. This measurement is determined by the distance between the attachment points (lugs) on the case and ensures the strap fits perfectly without play or excessive tension. To verify, measure the distance between the two internal metal poles on the rear lug of the case.

Which strap is most suitable for the Van der Gang 20004?

For the Van der Gang 20004, an alligator strap with vegetable tanning represents the most elegant choice, capable of enhancing the brushed stainless steel case. For daily professional use, a fine-grain calf leather is recommended; for informal or sporting contexts, NATO straps offer practicality. The choice depends on your intended use and the aesthetic balance you wish to achieve.

How do I change the strap on a Van der Gang 20004?

Changing the 20mm strap requires a spring bar remover tool to disengage the tension springs from the lugs. Insert the tool into the thin space between the strap and lug, gently lift to release the spring, then remove the old strap. Repeat on the opposite side. Install the new strap by reversing the procedure: ensure the springs are properly seated in their slots.

Can I use aftermarket straps on a Van der Gang 20004?

Yes, any strap with a 20mm lug width is compatible with the Van der Gang 20004. Quality aftermarket straps provide identical compatibility to original straps, provided the width is exact. We recommend verifying compatibility with the retailer before purchase to avoid construction discrepancies.

How long does a natural leather strap last on a watch like the 20004?

A quality leather strap with vegetable tanning can last 3-5 years with regular use and appropriate maintenance. Longevity depends on exposure to moisture, temperature fluctuations, and frequency of wear. Occasionally applying a vegetable leather conditioner and avoiding prolonged soaking significantly extends useful life. The patina that develops is part of the natural aesthetic evolution of the material.
