FAQ
What is the lug width of the Glashütte Original Senator 1-89-02-03-02-64?
The Glashütte Original Senator 1-89-02-03-02-64 features a lug width of precisely 21mm. This dimension is fixed by the case geometry and cannot be altered. To verify this specification yourself, measure the internal distance between the two lugs (where the strap seats): it must be exactly 21mm. This measurement is critical for ensuring proper strap fitment without overhang or lateral play.
Which strap material best suits the Senator 1-89-02-03-02-64?
For a timepiece of this aesthetic and technical stature, the strap must balance formal elegance with construction rigour. Alligator leather in vegetable tanning represents the most harmonious choice, as the natural grain of Nile crocodile complements the case's satin finish without competing visually with the dial. Alternatively, soft calf leather in cognac or chocolate tones develops a patina over time that amplifies the Germanic gravity of the movement. Both materials age beautifully and reward regular conditioning.
How do I change the strap on a Glashütte Original Senator?
The strap is secured via two spring bars (one at each lug). To remove: grip the watch firmly, position a spring bar removal tool beneath the bar, and press inward to compress the spring and release the strap. Avoid abrupt movements to prevent scratching the case. Installation is straightforward: align the new strap's holes with the spring bars and allow the springs to snap back into place. If uncertain, Atelier Casati Milano offers complimentary strap-changing service for purchases through our platform.
Are the straps sold on milanostraps.it compatible with the Senator 1-89-02-03-02-64?
Yes, all straps in our 21mm collection are tested and verified for compatibility with this lug width. Our range includes leather (alligator, calf, shell cordovan), NATO and rubber options, each manufactured to precise tolerances to eliminate play or misalignment. Every strap ships with detailed fitting instructions and can be personalised via our online configuration tool.
What is the expected lifespan of a leather strap for this model?
A quality leather strap's durability depends on tanning method, frequency of wear and maintenance. An alligator strap with vegetable tanning, worn daily, maintains structural integrity and visual appeal for 4–6 years before requiring restoration (fibula refurbishment or minor conditioning). Calf, being softer and more absorbent, shows visible patina within 2–3 years—a desirable characteristic. Rotating multiple straps (weekly basis) substantially extends each strap's lifespan by distributing natural wear.
