FAQ

What is the exact lug width of the Glashütte Original Senator 1-36-24-05-02-01?

The lug width of the Glashütte Original Senator 1-36-24-05-02-01 is 21mm. This measurement is taken internally between the two horizontal lugs that secure the strap to the case. Any strap with a 21mm lug width will be compatible with your Senator, regardless of material or finish.

Which strap is recommended for the Glashütte Original Senator?

The ideal strap depends on intended usage. For formal settings, we recommend alligator leather in dark brown or black, or European calf with vegetable tanning that will develop a natural patina. For versatile everyday wear, a Cordura 1000D NATO strap in anthracite or navy offers practicality without aesthetic compromise. In warm climates or for sports-oriented use, FKM rubber ensures durability and unaltered comfort.

How do you change the strap on the Glashütte Original Senator 1-36-24-05-02-01?

The strap is changed by removing the two side pins (spring bars) that secure it to the case. Use a dedicated spring bar tool to gently compress the internal spring of the pin, then extract the old strap. Insert the new strap into the lower slot, align the pin, and allow the spring to release—you will feel a confirmation click. Repeat for the lower pin. If uncertain, consult a professional watchmaker.

Are aftermarket straps compatible with the Senator 1-36-24-05-02-01?

Yes, any strap with a 21mm lug width is compatible with the Senator. High-quality aftermarket straps—such as those hand-crafted in alligator, shell cordovan, or vegetable-tanned calf—often offer construction and material quality comparable to or superior to the original. Always verify that the strap suits the case diameter (40mm) and features an appropriate deployante for your wrist circumference.

How long does a leather strap last on a watch like the Senator?

The lifespan of a leather strap depends on usage, climate, and tanning quality. A hand-crafted alligator or shell cordovan strap, properly maintained (dried after exposure to moisture, not left in prolonged direct sunlight), can last 5-8 years. European calf with vegetable tanning, being softer, typically lasts 3-5 years. The greatest wear occurs on the side in contact with the wrist. To extend life, alternate straps if you own multiple options.
