Strap for Legacy Machine LM101 Platinum

The lug width of the 51.PL.W is 20mm. This specification is determined by the constructive geometry of the case and must be strictly observed for proper strap installation. You can verify it by measuring the distance between the internal bases of both lugs using a digital calliper.

The ideal strap depends on your use case and aesthetic sensitivity. For a classical approach, alligator with vegetable tanning remains the most coherent choice with the watch's refined spirit. For equally high-quality alternatives, exceptional veal leather or a ballistic NATO offer technical compatibility and longevity. FKM rubber is recommended only if you desire a deliberately contemporary, contrasting aesthetic.

Strap change requires specific tools (spring bar removal tools or lever bars) and manual precision. If you lack experience, we recommend contacting Casati Milano (bespoke atelier by appointment), where our craftsmen will perform the operation with utmost care, protecting the platinum case from possible scratches. This is a delicate procedure that deserves professional handling.

Yes, any 20mm strap is technically compatible with the 51.PL.W's lugs. However, for a watch of this category, we recommend artisanal leather straps in full-grain fleur or technical-grade FKM rubber. Avoid cheap synthetic straps—the quality contrast would be evident and diminish your investment. Milano Straps offers curated selections specifically for this profile.

Durability depends on daily wear and leather quality. Vegetable-tanned alligator typically lasts 4-6 years with daily use, developing a noble patina over time. Vegetable-tanned veal tends to degrade faster (2-4 years), while FKM rubber offers superior longevity (8+ years) but requires periodic cleaning. Casati Milano provides restoration and replacement services to maintain your watch in optimal condition.
