NT 1 „Le bijou“

Precious jewel as a symbol of fine clockmaking

“For the gentleman the technology and for the lady the necklace”. Thus one might describe in brief the table clock NT 1 “Le bijou”, a variant of the NT 1 “L’amour” from our clock collection. For the first time in the history of our clockworks, the rim between the roots of the teeth and the arms of a wheel are set with precious stones. In the NT 1 “Le bijou” diamonds are set on the escape wheel - certainly the most delicate wheel of the entire clockwork.

108 sparkling diamonds

A veteran gem-setter works the escape wheel of this clock with great patience and manual dexterity. He sets 108 diamonds with a total w / vs 4.59 carats. Observing the moving escape wheel in the finished clock, the diamonds unobtrusively exude an indescribable fire. The table clock NT 1 “Le bijou” is a precious piece of jewelry. Handcrafted to perfection it is a highlight of fine clockmaking with a unique power reserve of 100 days.
