Strap for Zeitwerk Striking Time White Gold

The lug width of the Zeitwerk 145.029 is 21 mm. This dimension reflects the ergonomic proportions of the white gold 44.20 mm case and accommodates high-quality watch straps where leather thickness and construction harmonise with the Saxon craftsmanship of the timepiece.

Niloticum alligator with round grain and smoky-grey tonality is the ideal choice: the luminosity of the leather mirrors the white gold case, whilst the organic texture creates equilibrium with the geometric rigour of the dial. Vintage-tanned calf or polished burgundy shell cordovan offer refined alternatives for those preferring natural patina or a more pronounced chromatic contrast.

The Zeitwerk 145.029 uses standard pin-and-lug strap attachments: it is necessary to remove the two pins connecting the strap to the case lugs, an operation requiring a dedicated tool (spring bar removal tool). It is advisable to have the change performed by an authorised Lange service centre or specialised atelierium to prevent damage to the delicate white gold lugs.

Yes, provided the lug width is strictly 21 mm. Many universal straps are dimensioned for 20 or 22 mm and do not seat correctly in the case slots. We recommend bands constructed specifically for this width, crafted from noble materials (alligator, calf, shell cordovan) that respect the aesthetic and constructive integrity of the timepiece.

A high-quality alligator or calf strap, worn regularly, maintains structural integrity for 3–5 years. Longevity depends on frequency of wear, exposure to sunlight and humidity, and maintenance care. Vegetable-tanned leather tends to acquire natural patina over time; shell cordovan can last up to 7–10 years owing to superior material density. Casati Milano provides an 18-month warranty against manufacturing defects on all handcrafted straps.
