Strap for Senator Perpetual Calendar Red Gold / Silver

The Glashütte Original Senator 1-36-12-02-05-62 features a lug width of exactly 20mm. This measurement corresponds to the distance between the spring bar attachment points at the base of the case. Always verify the lug width before purchasing an aftermarket strap to ensure a perfect fit without lateral play.

For a rose gold Senator with a 42mm case diameter, we recommend alligator or vegetable-tanned calf leather straps in dark brown, cognac, or burgundy tones. Alligator enhances aesthetic sophistication through its natural scale texture, whilst calf leather develops a patina that evolves over time in parallel with the rose gold. Avoid excessive colour contrast such as pure black, which would create visual disruption against the warmth of the case.

To replace the Senator strap, use a spring bar tool to gently compress the elastic pins at the ansa ends. By tilting the strap slightly, the pins disengage from their seats in the case. The process is reversible: insert the new strap (20mm lug width) by snapping the pins into the corresponding seats. Proceed carefully to avoid scratching the rose gold case. If you lack experience, consult Atelier Casati Milano for professional replacement.

Yes, any strap with a 20mm lug width is compatible with the Senator 1-36-12-02-05-62. However, verify construction quality: for a timepiece of this calibre, we recommend artisanal leather straps in full-grain hide with reinforced stitching. Avoid budget straps that could compromise the aesthetic value and durability of the pairing. Milano Straps offers dedicated selections for 20mm lug widths of superior quality.

The lifespan of a leather strap varies depending on material and usage. An artisanal alligator or calf strap of quality craftsmanship, worn daily with regular maintenance, can last 3-5 years. The determining factor is care: keep the leather dry, avoid prolonged direct sunlight exposure, and occasionally apply leather-specific conditioners. Over time, the leather develops a natural patina that adds character. When the strap shows signs of wear, replacement preserves the integrity of the magnificent Senator.
