Strap for Senator Hand Date Stainless Steel / Black / Alligator / Pin

The lug width of the Glashütte Original Senator 1-39-58-01-02-04 is 20mm. This specification is standard for mid-sized models within the Senator collection and ensures compatibility with an extensive range of artisanal straps. To verify the lug width accurately, use a digital calliper positioned in the channel between the case and the lugs, or consult the official documentation accompanying your timepiece.

For the Senator 1-39-58-01-02-04, we recommend alligator or vegetable-tanned calf leather straps for formal contexts, as their regular grain pattern engages naturally with the geometric rigour of the stainless steel case. For daily versatile wear, shell cordovan in dark tones or a NATO strap in olive green offer practicality whilst maintaining the instrument's integrity. Vulcanised rubber straps are ideal if you desire functionality in humid environments without compromising on legibility.

To change the strap on a Glashütte Original Senator, you must remove the spring bars from the lateral channels of the case. Use a dedicated tool or very small screwdriver to gently compress the internal spring and release the bar terminus. Slide the old strap away by moving the bar out of the channel, then insert the new strap using the same procedure. For models featuring a deployante, you must first release the folding clasp mechanism before proceeding. If you lack experience, consult a specialist craftsman such as the Casati Milano atelier, available by appointment.

Yes, absolutely. All straps with a 20mm lug width are fully compatible with the Glashütte Original Senator 1-39-58-01-02-04. The artisanal straps from Milano Straps, handcrafted from superior-quality leather, alligator, shell cordovan, and textiles, integrate seamlessly with the case lugs without any functional compromise. Selecting an aftermarket strap represents an opportunity for aesthetic personalisation and seasonal rotation of your timepiece.

The lifespan of a leather strap varies according to material type, frequency of wear, and climatic conditions. A vegetable-tanned calf leather strap typically lasts 2–3 years with daily use; shell cordovan, owing to its superior density and natural moisture resistance, can reach 4–5 years. Alligator, whilst exceptionally elegant, remains more delicate and requires regular maintenance. To prolong strap life, avoid prolonged moisture exposure, do not submerge directly in water, and periodically apply a specialised conservation balm formulated for fine leathers.
