Armin Strom
Skeleton RG15-TF.5N— lug 20mm

The lug width of the Armin Strom Skeleton RG15-TF.5N is 20mm. Measure from the inner edge of one lug to the other using a digital caliper or flexible ruler. This specification ensures that any 20mm strap will fit precisely into the case lugs without play or misalignment.

For the Armin Strom Skeleton RG15-TF.5N, we recommend genuine alligator in dark brown or cognac tones: the uniform grain of the scales dialogues with the linearity of the skeletonized bridges, whilst rose gold finds perfect aesthetic resonance. Shell cordovan aged naturally is an excellent alternative for those seeking patina evolution over time.

Strap replacement requires removing the lug spring bars using a dedicated thin-blade tool. Gently insert the ferrule beneath the spring bar head, apply light downward pressure to compress the internal spring, then extract the bar. Insert the new strap into the lugs and reinsert the spring bar from the opposite side until it clicks into place.

Yes, any strap with a 20mm lug width is compatible. Milano Straps offers hand-crafted straps in leather, NATO, and rubber specifically designed for this measurement. We recommend straps of at least 1.4–1.6mm thickness to maintain correct visual proportions relative to the 43.4mm case.

A quality leather strap with artisanal stitching typically lasts 3–5 years with moderate daily use. Longevity depends on factors such as humidity exposure, frequency of wear, and maintenance. We recommend periodic conditioning with leather-specific creams and storage in dry environments to extend strap life.
