FAQ

What is the lug width of the Glashütte Original Senator 1-36-04-04-02-50?

The Glashütte Original Senator 1-36-04-04-02-50 features 21mm lugs. This is the standard width for 40mm cases and can be verified by measuring the interior channel between the two lugs with a digital calliper.

What is the best strap for the Senator 1-36-04-04-02-50?

An alligator strap in cognac or medium brown tones, or a vegetable-tanned calf leather, emphasise the dressy-formal identity of the Senator. Alligator is preferable for formal occasions due to its regular texture, whilst vegetable-tanned calf develops a natural patina over time, coherent with the manual-winding movement's heritage. Avoid rubber and elastomers, which are inconsistent with the Saxonian constructive philosophy.

How do I change the strap on my Senator?

Remove the strap by using a spring bar tool to extract the two lugs. Insert the tool into the small groove underneath each lug, apply gentle pressure until the internal spring yields, then withdraw the lug. Fit the new strap by reversing the procedure. Avoid hammers or brute force, which will damage the case.

Can I fit an aftermarket strap to this reference?

Yes. The Senator 1-36-04-04-02-50 accepts any 21mm strap (NATO, leather, rubber). The bespoke leather straps from milanostraps.it are fully compatible. Simply verify that the strap lugs align precisely with the lug channels, without play.

How long does a natural leather strap last on a manual-winding watch like the Senator?

A high-quality leather strap (alligator, vegetable-tanned calf) will last 3–5 years with daily wear, developing a characteristic patina over time. Longevity depends on exposure to moisture, perspiration and UV radiation. The milanostraps.it leather straps, hand-crafted, are designed to age with aesthetic dignity, requiring occasional conditioning treatments to preserve suppleness.
