Frequently asked questions

What is the lug width of the Van der Gang Watches Gents 20021?

The Van der Gang Watches Gents 20021 has a lug width of 20mm. This measurement represents the distance between the spring bar attachments on the case. A 20mm lug width requires a strap specifically cut for this dimension; standard 22mm straps will not fit. Always measure precisely using a digital calliper between the two metal rings protruding from the case.

What type of strap is recommended for the Van der Gang 20021?

Several options are recommended for the Van der Gang 20021 depending on intended use. Leather: vegetable-tanned calf leather for daily elegance with natural patination, or genuine alligator for formal wear with durable granular texture. Fabric: grey or navy blue NATO for versatility and sports practicality. Rubber: for water-intensive environments, swimming, or marine use. Choice depends on context and personal aesthetic preference. All straps must have lugs cut to 20mm.

How do you change the strap on this watch?

To change the strap on the 20021, spring bar pens and a dedicated removal tool or small flat screwdriver are required. Position the watch on a soft surface, apply slight pressure to the spring bar pin from underneath to compress the spring, and extract the old strap. Insert the new strap by sliding the compressed spring bar pin into the case lug holes, then allow the spring to expand naturally. Handle delicately to avoid scratching the case; avoid sharp tools and abrupt movements.

Are there aftermarket straps compatible with the Van der Gang 20021?

Yes, numerous quality aftermarket straps compatible with the Van der Gang 20021 exist, provided they are specifically manufactured for 20mm lugs. Artisanal brands such as those available on milanostraps.it offer leather straps (calf, alligator, shell cordovan), NATO, and rubber, precisely cut to 20mm. Before purchase, always verify that the vendor explicitly states the 20mm lug width, as this dimension is non-standard and an incorrect strap will be unusable.

How long does a leather strap last on a watch like the Van der Gang 20021?

Leather strap lifespan varies according to build quality, material type, intensity of use, and environmental conditions. Well-constructed vegetable-tanned calf leather lasts approximately 3-5 years of moderate daily wear. High-quality alligator may extend beyond 5 years. Factors shortening lifespan: intense sun exposure (accelerated ageing), frequent contact with undried fresh water, prolonged acidic perspiration, extreme temperatures. NATO fabric straps resist degradation far longer since textile does not deteriorate like leather. To maximise lifespan, keep the strap dry when possible, periodically clean with soft cloth, and occasionally treat with leather-specific balms.
