Frequently asked questions

What is the lug width of the Glashütte Original Senator 1-36-03-02-05-01?

The lug width of the Glashütte Original Senator 1-36-03-02-05-01 is 20 millimetres. This measurement represents the thickness of the attachment between case and strap and determines compatibility with aftermarket straps. You can verify this specification using a digital calliper inserted between the lugs, or by consulting the manufacturer's official documentation.

Which strap is most suitable for the Senator 1-36-03-02-05-01 in rose gold?

The ideal strap depends on usage and aesthetic preference. For maximum formal elegance, we recommend an alligator strap in black or dark brown with tone-on-tone stitching. For everyday versatility, calf leather crafted with vegetable tanning synchronises chromatically with the rose gold, developing a natural golden patina over time. For those seeking practicality and comfort, a NATO or quality rubber strap offers functionality without compromise.

How do you change the strap on a watch with a 20mm lug width?

Changing the strap is a straightforward operation requiring a specific tool: a spring bar tool. Position the watch on a stable surface and gently apply pressure to the small metal pin (spring bar) connecting the strap to the case until it retracts slightly. At that point, the strap disengages easily. Repeat the operation on the opposite side. To install the new strap, align the lug with the attachments and apply pressure to the spring bar until you hear an audible click.

Can I use a quality aftermarket strap on this Senator?

Yes, absolutely. Any strap with a 20mm lug width is mechanically compatible with the Senator 1-36-03-02-05-01. Overall quality depends on material craftsmanship and artisanal finishings. Quality alligator, calf, shell cordovan, vegetable-tanned, or NATO straps guarantee both mechanical compatibility and aesthetic harmony with the rose gold case.

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

Leather strap durability depends on construction quality and usage patterns: high-quality vegetable tanning typically lasts 3–5 years with daily wear, whilst developing a fascinating patina. Alligator tends to last longer (4–7 years) thanks to more resistant fibrous structure. Humidity, heat and sun exposure are primary accelerators of deterioration. Shell cordovan, due to its constructive density, can exceed 7 years of intensive use. Regular maintenance with dedicated creams significantly extends strap lifespan.
