Zeitwinkel
39mm Midsize 081° Rhodium— lug 18mm

The lug width of the Zeitwinkel 081° Rhodium is 18mm. This measurement is taken from the inner base of one lug to the other, perpendicular to the case plane. It is a specific dimension of the Midsize collection, intermediate between standard 16mm and 20mm formats, requiring purpose-designed straps.

The optimal strap depends on intended use. For elegance: dark brown alligator or black calf with vegetable tanning. For versatility: grey-blue NATO canvas. For sportivity and waterproofing: butyl rubber. The rhodium dial harmonises chromatically with diverse material palettes, allowing considerable aesthetic and functional freedom.

Position the watch case-down on a stable surface. Using a spring bar tool, apply inward pressure on the metal lug pin to release tension. Extract the spring bar, remove the old strap, and insert the new one, ensuring the pin aligns precisely within both 18mm lugs before full seating.

Yes, provided they are specifically dimensioned for 18mm lug width. Straps of different dimensions (16mm, 20mm) will not seat correctly without risk of lug damage. milanostraps.it offers a curated selection of artisanal 18mm straps, customisable and ready to ship.

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-5 years under regular daily wear. Longevity depends on solar exposure, humidity, wear frequency, and maintenance (conditioning with natural oils). Seasonal strap rotation significantly extends operational life.
