FAQ
What is the lug width of the Armin Strom Skeleton RG15-PF.5N?
The lug width of the Armin Strom Skeleton RG15-PF.5N is 20 millimetres. This dimension refers to the distance between the centres of the two holes where the strap passes through on the case. To verify compatibility with an aftermarket strap, measure with a calliper or ruler the distance between the lug holes: it must be exactly 20mm for a perfect fit.
Which strap is most suitable for the Armin Strom Skeleton RG15-PF.5N?
For the Skeleton RG15-PF.5N, we recommend straps in alligator or shell cordovan with vegetable tanning: the irregular grain or natural patina does not compete visually with the movement's transparency. For a formal approach, choose a deep cognac or dark brown; for casual contexts, NATO in heavy cotton or vulcanised rubber maintains coherence with the skeletonised aesthetic.
How do I change the strap on an Armin Strom Skeleton RG15-PF.5N?
Strap change is performed by removing the spring bars from the case lugs. Use a dedicated spring bar extractor tool: insert the tip into the horizontal groove of the bar, gently compress to apply pressure on the internal spring, and extract. Once the lugs are free, slide off the old strap and insert the new one, ensuring the spring bars sit completely. This operation requires care to avoid scratching the case.
Is there a compatible aftermarket strap for the RG15-PF.5N model?
Yes, any strap with a 20mm lug width is compatible with the Armin Strom Skeleton RG15-PF.5N. We recommend artisanal leather straps of quality: alligator, grained calf, shell cordovan. Always verify that the strap is fitted with standard spring bars (the same supplied with the watch) to ensure correct seating in the lugs. Milano Straps offers a complete selection of compatible 20mm straps.
How long does a leather strap last on this Armin Strom model?
A quality leather strap—alligator, calf, shell cordovan with vegetable tanning—lasts 2–4 years in daily wear, extendable to 5–6 years with regular maintenance. Longevity depends on climate (humidity accelerates ageing), frequency of use, and exposure to moisture and perspiration. Vegetable tanning develops a natural patina that improves aesthetics over time. Rotating multiple straps reduces wear and extends the life of each.
