Strap for Senator Perpetual Calendar Red Gold / Silver / Rubber / Folding

The lug width of the Glashütte Original Senator 100-02-22-05-04 is 20 millimetres. This dimension is specific to the 42mm case and requires straps constructed with precise tolerances to ensure attachment to the spring bars without lateral play.

For a timepiece of this calibre, we recommend dark brown alligator with reddish undertones, which complements the rose gold case beautifully. Alternatively, shell cordovan in oxblood offers superior structural density and develops authentic patina over time, ideal for those seeking longevity and character.

Position the watch on a soft pad with the case facing downwards. Locate the small hole in the spring bar and gently press with a dedicated spring bar tool to retract it. Simultaneously extract the old strap and insert the new one, ensuring the spring bar clicks into position. Repeat on both lugs.

Yes, provided the lug width is precisely 20 millimetres and the strap thickness is proportionate (medium-full). Avoid straps of excessive thickness, which would create aesthetic discord with the case. Milano Straps provides straps specifically constructed for this dimension, tested on compatible models.

A superior quality alligator strap lasts 3–5 years under regular use (worn 5–7 days weekly). Shell cordovan and vegetable-tanned calf offer 4–7 years of wear, depending on sun exposure and humidity. The patina evolves rather than degrades, potentially requiring conditioning with a specific balm after 2–3 years.
