Strap for Modello Due U2-MMC Morgan Motor Company

The Unimatic Modello Due U2-MMC features a lug width of 22 mm, measured according to ISO 1385 standard between the internal points of both lugs. This dimension ensures broad compatibility with contemporary aftermarket straps while maintaining rigorous engineering tolerances.

The Modello Due U2-MMC demonstrates its industrial character through dark brown vegetable-tanned leather or charcoal NATO straps. For intense daily use, FKM rubber straps preserve the tool-oriented aesthetic; for refined sobriety, vegetable-tanned leather develops a patina that complements the satin-finished 316L steel case.

Remove the spring bar positioned at the lug extremities using a dedicated strap-removal tool or small flat-head screwdriver. Compress the spring towards the case centre to release it from its seat, then extract the strap. Insert the new strap by aligning the holes with the lugs, reposition the spring bar, and verify it clicks completely at both points.

Yes, the 22 mm lug width of the U2-MMC ensures full compatibility with carefully constructed aftermarket straps. Verify that the strap is rated for this width and that the thickness does not exceed 4 mm to avoid excessive spring-bar tension and ensure comfortable wear.

A quality leather strap, with proper maintenance, typically lasts 18–24 months of intensive daily use. Longevity depends on tanning quality, exposure frequency to direct moisture, and applied care. Vegetable-tanned straps age elegantly whilst weakening structurally; synthetic versions maintain greater longevity but develop less aesthetic patina.
