Frequently asked questions

What is the lug width of the Glashütte Original Senator 1-58-01-01-04-50?

The Glashütte Original Senator 1-58-01-01-04-50 features a lug width of 21mm, an exclusive dimension within the Senator family. This measurement is uncommon in the watch market and requires straps specifically constructed to this proportion. To verify the width, place a ruler between the lugs at their base, where the strap sits against the case.

Which strap do you recommend for the Senator 1-58-01-01-04-50 in white gold?

For the Senator 1-58-01-01-04-50, we recommend alligator leather with vegetable tanning in black or deep brown for formal occasions, or shell cordovan for a patina that matures with time. A NATO strap in heavy cotton offers daily practicality, while a bespoke FKM rubber strap guarantees resistance and waterproofness. Your choice depends on use context and skin tone.

How do you change the strap on the Senator 1-58-01-01-04-50?

Position the watch with the dial facing downward. Using a small removable pin or dedicated tool, gently push the lug pins from the inside outward, one at a time. Avoid hammers or excessive pressure: the pin is tempered steel and cannot deform. Once the old strap is removed, thread the new strap by aligning its central hole with the pin, then reposition the pin on the opposite side.

Can I use an aftermarket strap compatible with the Senator 1-58-01-01-04-50?

Yes, provided it strictly respects the 21mm lug width. Straps constructed to this width by specialised manufacturers (such as Milano Straps) guarantee construction precision and material quality appropriate to your watch's level. Avoid generic options: a poorly proportioned strap compromises the aesthetic harmony of your white gold case.

How long does a leather strap last on the Senator 1-58-01-01-04-50?

A quality alligator or calf strap, worn daily, lasts 3-5 years before requiring repair or replacement. Longevity depends on environmental humidity, cleaning frequency, and usage intensity. Shell cordovan ages more slowly and can last 5-7 years. FKM rubber resists indefinitely if cleaned regularly. Regular maintenance—soft cloth cleaning and annual conditioning for vegetable-tanned leathers—significantly extends strap life.
