Lot 43. Moritz Grossmann : Tremblage Only Watch

Tremblage involves a surface being finished by hand using a range of engraving burins. The tools are moved across the metal in a trembling motion, which is also where the name comes from, with the French ‘tremblant’ meaning ‘to tremble’ in English.

It gives rise to a rough but matt effect that dampens the incident light on the dial of the special model and makes the tremblage surface appear beautifully matt.
