About the Nano family

The Nano Foudroyante EWT is Greubel Forsey's smallest watch. Presented for the brand's 20th anniversary as part of its Experimental Watch Technology work, it has a foudroyante, a hand that jumps rapidly around a small dial to show fractions of a second.

As a very recent and rare model, buyers will expect the full set, the certificate and the original warranty.
