Frequently asked questions

What is the lug width of the Glashütte Original Senator 1-36-04-01-02-71?

The lug width of the Senator 1-36-04-01-02-71 is 21 millimetres. This measurement, taken perpendicular to the lugs' interior faces, accommodates straps specifically dimensioned for this specification. Always ensure that the strap shoulders do not exceed the case profile.

Which strap is best suited for the Senator 1-36-04-01-02-71?

The Senator pairs ideally with alligator satin-finished straps, vegetable-tanned calf leather, or FKM rubber. Stone-grey or tobacco-brown alligator emphasises the Saxonian sobriety of the case. Calf leather develops natural patina over time. Grey-dark or navy-blue rubber offers daily versatility. Avoid aggressive synthetic textures that would contrast with the minimalist design.

How do I change the strap on my Senator?

To change the strap on the Senator 1-36-04-01-02-71, you must remove the lug pins using a dedicated pin remover or gentle tool. Position the watch face-down on a soft cloth. Apply slight upward pressure on the pin whilst extracting it laterally. Once freed, slide out the old strap and insert the new one, repositioning the pins. We recommend having this performed by a trusted watchmaker.

Can I use an aftermarket strap on this model?

Yes, any strap with a 21-millimetre lug width is compatible with the Senator 1-36-04-01-02-71. The artisanal 21mm straps from milanostraps.it are engineered for structural and aesthetic compatibility with this specification. Verify that the strap is crafted from noble materials—alligator, calf, FKM rubber—to maintain the Senator's stylistic integrity.

How long does a leather strap last on the Senator?

Leather strap longevity depends on usage, tanning method, and maintenance. A vegetable-tanned calf strap, with daily wear and proper care, typically lasts 5–10 years before replacement. Alligator, owing to its fibrous structure, tends to endure slightly longer. Applying specialist conditioners every 12–18 months and keeping the strap dry significantly extend usable lifespan.
