Frequently asked questions

What is the lug width of the Elka Watch Co. X-Series X02-0901?

The lug width of the X02-0901 is precisely 20.00 mm. This represents a specific design specification that requires a strap manufactured exactly to this dimension. Using adapters or straps of different widths is not recommended, as it would compromise the visual proportions between the case and the accessory.

Which strap is most suitable for the Elka Watch Co. X-Series X02-0901?

The choice depends on your intended use case. For formal wear, we recommend alligator with vegetable tanning or English calf leather; for sporting and maritime contexts, a NATO strap in technical canvas or a fluorosilicone rubber strap. Shell cordovan represents the intermediate solution: elegant, durable, and develops a patina that improves with time.

How do I change the strap on an Elka Watch Co. X-Series X02-0901?

Strap replacement is performed by extracting the spring bars located beneath the lugs. Using a dedicated tool, insert the tip into the lateral slot of the spring bar, compress the spring, and extract the bar. Next, align the new strap's holes with the lug holes, reintroduce the spring bar, and verify secure locking. The operation takes approximately 2-3 minutes and requires no specialised technical skills.

Can I use aftermarket straps compatible with the 20mm lug width?

Yes, you can. However, we recommend selecting high-quality straps manufactured specifically at 20 mm, as this dimension is not standard in the mainstream market. At milanostraps.it, you will find a curated selection of leather, NATO, and rubber straps, all handcrafted to exact specifications to guarantee dimensional precision and perfect compatibility.

What is the average lifespan of a leather strap for the Elka Watch Co. X-Series X02-0901?

A high-quality leather strap (alligator, calf, shell cordovan) manufactured for the X02-0901 has a lifespan of 3-5 years with daily use, provided regular maintenance is performed: gentle cleaning with a damp cloth, avoidance of prolonged direct water exposure, and annual conditioning with specialist creams. Vegetable-tanned leather tends to age more gracefully than industrial treatments, developing a patina that increases the aesthetic value of the accessory over time.
