Strap for Senator Tourbillon Edition Alfred Helwig White Gold / Silver / Alligator / Folding

The lug width of the Senator 1-94-03-05-04-50 is 21mm. This dimension is determined by the width of the case at the lug attachment point and represents the exact distance between the two pins of the case. To verify compatibility, measure the physical distance between the case lugs using a digital calliper.

For this white gold timepiece, we recommend alligator straps in superior quality (French grade A) or vegetable-tanned calf leather. Alligator offers maximum chromatic elegance and develops a beautiful patina over time; calf leather provides more pronounced texture and versatility across seasons. For informal daily wear, silk biological NATO represents a sober technical solution.

The strap is changed by removing the lateral spring bars. Use a dedicated spring bar tool, inserting it gently into the side groove of the case. Push slightly on the bar to retract the internal spring, then extract the bar from the case. Insert the new strap and reinsert the bar until it clicks into place. Always verify complete insertion before wearing the watch.

Yes, any strap with a 21mm lug width is compatible. Bespoke artisanal straps allow you to fully customise the watch whilst maintaining proportional harmony and construction quality. We recommend straps with a thickness of 1.3-1.5mm and lugs compatible with the Senator's specific attachments, always verifying precise dimensions before purchase.

A quality strap (grade A alligator or vegetable-tanned calf) typically lasts 3-5 years with daily wear, provided it is maintained correctly. Longevity depends on sun exposure, humidity, frequency of changes, and tanning quality. Alligator tends to last slightly longer than calf. Periodic maintenance (gentle cleaning, natural wax treatment) significantly extends durability.
