Strap for Zeitwerk Striking Time Pink Gold

The Zeitwerk 145.032 features a lug width of 21 millimetres. This specific measurement is the only compatible size for this model and derives from the proportion between the case diameter (44.20 mm) and the depth of the jumping hour movement. Always verify the measurement by inserting a ruler between the case lugs at their deepest point before ordering an aftermarket strap.

Alligator in dark brown remains the most congruent choice aligned with the Zeitwerk's aesthetic philosophy. The fibrous structure of alligator leather mirrors the geometric logic of the dial, whilst the colour does not compete with the rose gold. Alternatively, shell cordovan in deep burgundy develops natural patina over time, or vegetable-tanned calf for those preferring a softer option.

The Zeitwerk 145.032 uses fixed lugs (not rotating Aquanaut-type lugs). Remove the watch, obtain a spring bar tool, position it delicately beneath one lateral pin from the lower case side, and gently prise upward to release the spring bar. Repeat on the other side. Insert the new strap by positioning one pin first, then the other, ensuring the spring bar is correctly engaged. This is a delicate operation; novices should avoid attempting it themselves.

Yes, it is possible. However, it is essential to order a strap of the highest quality with a lug width rigorously measured at 21 mm and a deployant clasp in 18-carat rose gold (not stainless steel). Casati Milano produces custom straps with direct consultation to guarantee perfect compatibility and craftsmanship worthy of the Lange movement. Online, pre-selected 21mm straps are available.

The lifespan of a leather strap depends on material and construction. Quality alligator easily surpasses 4–5 years of daily wear without significant deformation. Shell cordovan can last 6–7 years due to its natural fibre density. Vegetable-tanned calf tends to wear more rapidly (2–3 years) because vegetable tanning is less durable than chrome tanning. In all cases, Casati Milano offers a guarantee against manufacturing defects for 18 months.
