Frequently asked questions

What is the lug width of the Van der Gang Watches Gents 20044Z?

The Van der Gang Watches Gents 20044Z features 20mm lug width (shoulder to shoulder, measured on the inner face). This measurement must be respected with precision when selecting an aftermarket strap to ensure stable fitting and eliminating play.

Which strap is recommended for the Van der Gang 20044Z?

For a 44mm chronograph with ETA 7753 movement, we recommend black or brown alligator for formal contexts, shell cordovan for longevity and evolving patina, or Cordura NATO for robust daily wear. The choice depends on your wearing context and desired tactile relationship with the strap.

How do I change the strap on the Van der Gang 20044Z?

Straps are changed by using a small spring bar tool to gently open the spring bars—the metal fasteners that hold the strap in place at the lugs. Insert the tool tip into the gaps of the spring, lift with gentle rhythmic movements until the latch opens, then remove the old strap and insert the new one, ensuring the spring bars click securely into position.

Can I use an aftermarket strap on this watch?

Yes, any quality-certified strap with a 20mm lug width is compatible with the Van der Gang 20044Z. Always verify that the strap has been measured shoulder-to-shoulder on the inner face of the lug. Reputable brands guarantee tolerances within ±0.2mm, preventing play or insertion difficulties.

How long does a leather strap last on the Van der Gang 20044Z?

Leather strap longevity depends on tanning and daily wear. Alligator or vegetable-tanned calf typically lasts 3–5 years of frequent wear, with patina improving over time. Shell cordovan can exceed 7–10 years. Periodic maintenance (conditioning with specific creams, air drying in natural conditions) significantly extends durability.
