Strap for Senator Perpetual Calendar Stainless Steel / Salmon / Bracelet

The lug width is 20mm. This measurement must be verified by measuring the space between the two attachment lugs extending from the case: from the inner shoulder of the left lug to the inner shoulder of the right lug. An incompatible strap will not fit into the attachments or will leave unsightly lateral gaps.

The choice depends on intended use and desired aesthetics. For maximum formality and timelessness, an alligator leather with vegetable tanning and pronounced grain is ideal as it patinas over time. For daily elegance, Italian calf leather vat-dyed offers a finer, more homogeneous grain. For versatility, a vulcanised rubber strap ensures longevity in humid climates without sacrificing refinement.

The Senator features an integrated lug (non-interchangeable), so the strap is attached to the fixed lugs of the case. A strap removal tool is used to thread the strap into the two attachment rings, ensuring it enters fully into the slots. We recommend having this operation performed by a professional watchmaker to avoid damaging the case finish or delicate details.

Yes, provided they strictly respect the 20mm measurement. However, not all standard 20mm straps are aesthetically compatible with the Senator due to the need to preserve the visual harmony of the case and integrated lugs. We recommend artisanal quality straps where stitching and material reflect the construction quality of the watch.

A high-quality alligator or calf leather strap with vegetable tanning typically lasts 3–5 years with regular use (5–7 days per week), provided it receives periodic maintenance: avoid prolonged moisture, apply a specific balm occasionally, and have attachments and stitching inspected every 2–3 years. Durability also depends on climate conditions and leather type.
