Strap for Senator Excellence Panorama Date Moonphase Stainless Steel / Blue / Alligator - Folding

The lug width is precisely 21 millimetres. This non-standard dimension requires specially manufactured straps, as most workshops operate on conventional widths of 20 or 22 millimetres. To verify: position a digital calliper between the two metal lugs protruding from the case, perpendicular to their axis.

We recommend three options in order of aesthetic prevalence: (1) Dark brown alligator, which amplifies formal refinement and dialogues with German constructive geometry; (2) Vegetable-tanned calf leather in Cognac or mahogany tones, which develops rich patina over time; (3) Robust canvas NATO, for those preferring sporting versatility. Choice depends on intended use and dial tonality.

Strap replacement requires a dedicated spring bar extractor tool or consultation with a specialist watchmaker. The two metal pins securing the strap must be pushed laterally to release the previous strap, then the new strap is inserted by passing the pins through the appropriate holes in the case. We always recommend entrusting this operation to professionals to avoid scratching the case.

Yes, provided the lug width is precisely 21 millimetres. Standard 20 or 22 millimetre straps will not fit correctly. MilanoStraps offers specialised straps for this width, crafted in premium leather, NATO, and rubber, compatible with the Senator's lugs and ready to ship.

A premium leather strap – alligator, shell cordovan, or vegetable-tanned calf – typically lasts between 4 and 8 years with moderate use and appropriate maintenance. Longevity depends on frequency of wear, sun and moisture exposure, and care in cleaning. A vegetable-tanned strap develops patina during ageing, becoming softer and characterful; alligator maintains a more rigid and formal structure over time.
