Housed in a 40mm white gold case, this replica ultra thin master white 40mm tourbillon pushes the Master Ultra Thin concept into haute horlogerie territory. White gold provides a cooler, denser presence on the wrist than stainless steel, and the slightly larger 40mm diameter gives the tourbillon aperture at six o’clock more room to breathe. The manual-winding caliber keeps the case profile thin by eliminating the automatic rotor. The result is a dress watch that happens to contain one of the most visually dramatic complications in mechanical watchmaking.

White gold looks similar to steel in photographs but feels noticeably heavier in hand. That density translates to a weighted, substantial wrist presence that steel at the same dimensions cannot deliver.

What Collectors Notice

The 40mm sizing is one millimeter larger than most Ultra Thin Master references, and that extra space changes the visual balance around the tourbillon window. Collectors pay attention to the cage rotation speed, the finishing on the bridge holding the tourbillon, and whether the aperture frame integrates cleanly with the dial surface. Jaeger-LeCoultre has been producing tourbillons since 1929, giving the manufacture nearly a century of refinement in this specific complication.

The 1362511 automatic reference offers the same design ethos in steel without the tourbillon, serving as a useful baseline for comparison.

This vs Other Versions

Compared to the enamel-dial tourbillon in this collection, the white gold version takes a more restrained visual path. The dial stays clean and unadorned, letting the tourbillon cage and the metal itself carry the statement. If you want the tourbillon experience delivered through material quality rather than decorative craft, this replica ultra thin master white 40mm edition is the reference that prioritizes substance over surface.
