The Senator 1-36-59-03-02-01, seen from the bench

The Glashütte Original Senator Excellence 1-36-59-03-02-01 is a stainless steel dress watch with a 40mm case and 20mm lug width, embodying Saxon watchmaking tradition. Powered by the Glashütte Original 36-01 manual-wind caliber, it features hours, minutes, and small seconds displayed through a sapphire caseback. The satin-finished steel case reflects classical design principles without excessive polish, positioning itself as an intellectual tool rather than jewelry, suited for those valuing understated construction.

Frequently asked questions

What is the lug width of the Glashütte Original Senator 1-36-59-03-02-01?

The lug width is 20mm. This measurement must be verified by placing a calliper from the centre of one lug hole to the centre of the opposite hole, excluding the lug material itself. This is the exact reference for selecting compatible straps.

What is the best strap for the Senator 1-36-59-03-02-01?

Alligator leather in dark brown or black tones, or vegetable-tanned calf that develops patina over time, enhance the aesthetic rigour of the silver dial. For summer wear, an O.D. nylon NATO or FKM rubber maintains technical seriousness. Choice depends on daily use and preference for patina development.

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

Strap replacement requires a specific spring bar tool to extract the lug pin. Position the metal compass in the designated holes, compress the internal spring slightly to release the pin, then extract it from the lug. Repeat on the opposite side. Insert the new strap by sliding the pin through the holes until the safety click engages.

Can I use an aftermarket strap compatible with the Senator?

Yes, provided the width is precisely 20mm and the spring bar holes are correctly dimensioned. Verify that the strap holes accommodate the lug pin without lateral play. Milano Straps offers 20mm straps custom-made for this specific compatibility, in artisanal leather and technical materials.

How long does a leather strap last on a watch worn daily?

Durability depends on tanning method and thickness. A quality vegetable-tanned calf strap withstands 3-5 years of daily wear whilst developing aesthetic patina. Quality alligator can last 5-7 years. Longevity increases if the watch is not worn in very humid environments or overnight.
