Strap for Sixties Stainless Steel / Glacier Blue / Pin / Annual Edition

The lug width is 18 mm. This measurement is determined by the integrated lugs in the case and cannot be modified. To verify strap compatibility, measure the distance between the two lugs: it must be exactly 18 mm.

Alligator leather with vegetable tanning represents the ideal choice, as its natural texture dialogues perfectly with the minimalist aesthetics of the brushed case. Alternatively, vegetable-tanned calf leather offers elegance and controlled aging; shell cordovan introduces sophisticated material warmth. For versatile daily wear, a heavyweight cotton NATO strap remains functionally sound whilst maintaining the minimalist spirit of the design.

The Sixties uses a standard system with rectangular lug attachments. Gently rotate the watch and locate the lug on one side. Using a spring bar removal tool, press lightly inward on the lug to release the internal spring clip, then slide the old strap outward. Insert the new strap by aligning the passant with the lug, pressing until the spring clip snaps perceptibly into place. Repeat on the opposite side.

Yes, it is fully compatible to use high-quality aftermarket straps, provided the lug width is exactly 18 mm. Milano Straps offers a curated collection of artisanal straps specifically crafted for this dimension, with guaranteed construction quality and carefully selected materials. Always verify that the strap is designed for 18 mm lugs before purchase.

A high-quality leather strap, such as vegetable-tanned versions, typically lasts 2 to 4 years with daily wear and appropriate care. Durability varies based on wear frequency, climate conditions, and maintenance (drying after humidity exposure, avoiding excessive heat). With proper maintenance, the strap develops a desirable patina that enhances its aesthetic value over time. NATO leather, owing to its more robust textile structure, can last 4-6 years.
