Frequently asked questions

What is the lug width of the Glashütte Original Senator 1-36-02-01-02-61?

The Glashütte Original Senator 1-36-02-01-02-61 features a 20mm lug width. This measurement represents the horizontal distance between the two spring bar attachment points and is essential for selecting compatible straps. You can verify it by measuring directly from the inner shoulder to the opposite inner shoulder on the case.

Which strap is recommended for the Senator 1-36-02-01-02-61?

For the Senator Glashütte Original, we recommend high-quality materials depending on your intended use: natural-tinted alligator for formal occasions, shell cordovan for those who appreciate a dramatic patina development over time, vegetable-tanned leather for a sustainable approach, or silk and cotton NATO for a contemporary interpretation. Technical rubber remains ideal if you intend to utilise the perpetual calendar in sporting contexts.

How do I change the strap on a Glashütte Original Senator?

Strap replacement on the Senator occurs via the spring bars: position the watch in a dedicated stand, remove the original strap by depressing each spring bar downward in turn with a dedicated tool (spring bar tool), then insert the new strap by aligning the holes to the spring bar ends. Milano Straps provides comprehensive guidance on replacement and offers bespoke customisation services.

Can I use an aftermarket strap on a Glashütte Original Senator?

Yes, it is possible to use compatible aftermarket straps provided they respect the 20mm lug width specification. Milano Straps offers a curated selection of artisanal leather, NATO and rubber straps, all available in 20mm and customisable according to your aesthetic and chromatic preferences.

How long does a leather strap last on a watch like the Senator?

The longevity of a leather strap depends on material quality, frequency of use and maintenance practices. A premium-grade alligator or shell cordovan can endure 5 to 10 years with moderate daily wear. Vegetable-tanned leather tends to develop patina more rapidly (12–24 months) but remains functional for extended periods. We recommend rotating at least two straps to significantly extend the lifespan of each.
