FAQ
What is the lug width of the Glashütte Original Senator 1-37-01-05-02-35?
The lug width of the Senator 1-37-01-05-02-35 is 21mm. This measurement represents the physical distance between the two case lugs where the strap attaches. Verifying this dimension before purchasing a replacement strap is essential, as an incorrect width will cause lateral movement and risk of accidental detachment. On milanostraps.it, you'll find all compatible 21mm straps available in leather, NATO, rubber, and other materials.
Which strap should I choose for the Glashütte Original Senator 1-37-01-05-02-35?
Strap selection depends on intended use and personal aesthetic preference. For formal and office wear, we recommend alligator or vegetable-tanned calf leather in dark tones (black, burgundy) paired with a deployante clasp. For daily versatility, NATO in grey or blue cordura provides comfort and durability. For sport-elegant applications, shell cordovan with an ardillon buckle develops unique patina as it ages. The stainless steel Senator also accommodates technical rubber with silk underlining during humid seasons.
How do I change the strap on a Glashütte Original Senator 1-37-01-05-02-35?
Obtain a spring bar tool with blunt ends to avoid scratching the case. Position the watch face-down on a soft cloth. Insert the tool into the space between the case lug and the current strap's lug hole, pressing gently downward to compress the internal spring. Once released, remove the current strap. Align the new strap and reinsert the spring bar by compressing again. Verify secure attachment on the opposite side by applying gentle tension. Atelier Casati Milano offers this service complimentary on any strap purchased from milanostraps.
Can I use an aftermarket strap on a Glashütte Original Senator 1-37-01-05-02-35?
Absolutely. Many luxury watch owners prefer artisanal aftermarket straps to OEM (Original Equipment Manufacturer) options because they allow greater aesthetic personalisation and subjective expression. Simply verify that the lug width is 21mm and thickness is 3.5–4mm. Milanostraps manufactures straps in Italian leather, NATO fabric, and rubber certified for compatibility with the Senator and other Glashütte Original references.
How long does a natural leather strap last on a watch like the Senator?
A natural leather strap under daily use has an average lifespan of 4–7 years, depending on material type, tanning method, and environmental conditions. Vegetable-tanned leather develops a natural patina that enhances appearance over time. Alligator leather is more resilient and may last 10–12 years. Avoid prolonged water exposure and direct UV radiation. Clean periodically with a damp soft cloth and occasionally apply mink oil to maintain flexibility. Atelier Casati Milano offers strap restoration services by appointment.
