Strap for x Eddy Jaquet Legacy Machine Split Escapement Journey To The Centre Of The Earth

The MB&F Legacy Machines 04.RL.W6 features a lug width of 20mm, measured from inner edge to inner edge of the lugs on the case. This dimension is critical for selecting a compatible strap without risking damage to the red gold case through forced fitting.

For the 04.RL.W6 in red gold, we recommend vegetable-tanned alligator leather in cognac or chocolate brown tones: the natural texture of alligator skin engages aesthetically and philosophically with the raw architecture of the visible movement and the warmth of red gold. Alternatively, vintage calf leather with aged patina maintains elegance without chromatic competition.

Strap replacement on the Legacy Machines 04.RL.W6 is executed by disengaging the spring bars from the case using a dedicated spring bar tool or gentle lever. The red gold lugs require measured caution: position the tool parallel to the movement and apply controlled pressure. Once disengaged, align the new strap's holes with the lugs and re-insert the spring bars until you perceive the audible click.

Yes, it is entirely feasible to equip your 04.RL.W6 with an artisanal aftermarket strap of 20mm width. We recommend verifying precision measurement—neither 19mm nor 21mm—and ensuring the lug ends are smooth to avoid scratching the delicate red gold spring bars. Milano Straps supplies straps specifically tested on this reference.

A premium leather strap (alligator, calf, shell cordovan) on a daily-worn watch typically remains serviceable for 18–36 months before requiring replacement. Longevity depends on environmental humidity, skin perspiration, intensity of use, and tanning quality. A vegetable-tanned strap ages more elegantly than industrially produced equivalents, developing patina instead of degradation.
