Description

In honor of the 10th anniversary of The PuristS, MB&F proudly presented the HM3 Chocolate Frog, a limited edition of just 10 pieces available only through www.PuristSPro.com. While haute horlogerie is usually a restrained and serious business, MB&F was created to inject a child's sense of awe and sense of playfulness into high-end watchmaking and the HM3 Chocolate Frog certainly does that . . . and more!

The protruding eyes of the (amphibian) frog enable it to see in many directions without having to turn its head. The bulbous domes of the HM3 Chocolate Frog have the opposite, but no less important, feature of enabling the time to be easily seen from many angles without having to turn the wrist. The Frog differs substantially from HM3 in that it is the aluminum domes that rotate under the sapphire crystals in the Frog, whereas it is the hour and minute hands that rotate around their respective stationary cones on HM3.

Rotating domes of this size and shape posed MB&F with a number of technical challenges. The hour and minute domes are machined from solid aluminium - chosen for its optimal strength to weight ratio. The domes weigh in at just over 0.5g. They are milled first from the outside and then the inside to arrive at a paper-thin wall thickness of just 0.28 mm, which reduces their energy requirements to an absolute minimum
