Frequently asked questions

What is the lug width of the Glashütte Original Senator 1-37-01-05-02-06?

The lug width of the Glashütte Original Senator 1-37-01-05-02-06 is 21 mm. This measurement represents the internal distance between the two spring bar pins that secure the strap to the case. It is essential to verify this specification before purchasing an aftermarket strap, as an incorrect measurement would compromise the fit and overall aesthetic integrity of the timepiece.

Which type of strap is most suitable for the Glashütte Original Senator 1-37-01-05-02-06?

The most suitable straps for the Senator 1-37-01-05-02-06 are: alligator leather (for a formal, classical appearance), vegetable-tanned calf (for versatility and conscious ageing), shell cordovan (for artisanal elegance), and NATO in nylon or canvas (for sportwear applications). The choice depends on daily or occasional wear and dial colour. Consult Atelier Casati Milano for a personalised evaluation.

How do I change the strap on a Glashütte Original Senator 1-37-01-05-02-06?

Changing the strap on the Senator involves removing the two lateral spring bar pins that hold the strap to the lugs. Use a dedicated tool (spring bar tool) or a small flat-head screwdriver, applying gentle pressure on the internal spring to slide the pin out of its seat. Insert the new 21 mm strap, ensuring the pin is fully secured. If uncertain about the procedure, consult a certified watchmaker.

Can I use an aftermarket strap compatible with the Glashütte Original Senator 1-37-01-05-02-06?

Yes, provided the lug width is precisely 21 mm and the strap has been constructed with quality materials (vegetable-tanned leather, natural tannins, artisanal finishes). Milanostraps.it offers a curated collection of 21 mm compatible straps, crafted by Italian artisan masters. Each strap is tested to ensure proper fit and durability.

How long will a leather strap last on my Glashütte Original Senator 1-37-01-05-02-06?

The lifespan depends on leather quality and usage conditions. An alligator or premium calf strap, worn weekly, typically lasts 3 to 7 years before aesthetic replacement becomes desirable (tears, thinning). With vegetable tanning, the leather improves visually over time, developing an appreciated patina. Store the strap in a dry environment and protect it from prolonged moisture exposure.
