FAQ

What lug width does the Elka Watch Co. X-Series X12-0804 have?

The Elka Watch Co. X-Series X12-0804 features a lug width of 20.00mm. This measurement refers to the internal distance between the two lugs (horns) of the case where the strap attaches. It is essential to verify this dimension with a digital calliper before purchasing an aftermarket strap, as even a variation of a few tenths of a millimetre could compromise the fit.

What is the best strap for the Elka Watch Co. X-Series X12-0804?

The choice depends on usage context and aesthetic preference. For a classic-elegant setting, we recommend Nile alligator with vegetable tanning, which develops a golden patina over time. For a contemporary sport approach, a NATO strap in grey Cordura fabric maintains balanced proportions. For maximum functionality, an FKM rubber strap offers complete water resistance and durability in high-wear environments.

How do you change the strap on an Elka Watch Co. X-Series X12-0804?

The strap is changed using a spring bar tool (a specialised implement with two curved ends). Position the watch so one lug is accessible, insert the tool end into the hole beneath the lug to release the internal spring, then remove the worn strap. Insert the new strap by aligning one side first, then press the second side until it clicks into place. Ensure the strap does not bend the lugs during operation.

Are aftermarket straps available that are compatible with the Elka Watch Co. X-Series X12-0804?

Yes. The Elka X12-0804 accepts any commercially available strap with a 20mm lug width. Whilst many suppliers exist online, we recommend verifying construction quality, the shaping of the ends (which must fit the lugs without forcing), and material integrity. At milanostraps.it, a curated selection of artisanal 20mm straps is available in leather, NATO, and rubber, all tested for compatibility.

How long does a leather strap last on an Elka Watch Co. X-Series X12-0804?

The lifespan of a leather strap depends on intensity of use, exposure to moisture, and the tanning method employed. A high-quality vegetable-tanned alligator strap, worn daily, maintains structural integrity for 3–5 years before requiring replacement. Calf leather typically lasts slightly less (2–4 years) due to its more delicate grain. Regular maintenance (cleaning with a damp cloth, thorough drying, conditioning with natural oils every 6–8 months) significantly extends strap life.
