Reference 3730 is one of those watches that best incarnates the ethos of the Ellipse in the 1970s. In production for about one and a half decades (1976-1990), thanks to its large 38x31mm size and lug-less design it allows the beholder to admire the perfectly proportioned case in all of its unabashed geometrical beauty. On top of that, it appears that the model was predominately executed with onyx dials, truly incorporating the experimentalism that is typical of the 1970s. Compounding to its mystique, the model appears to be incredibly rare: so far less than 10 pieces were identified, while the present example is fresh-to-the-market.

In this specimen, the wonderfully preserved onyx dial creates a pitch black pool of perfect glossiness which markedly contrasts with the warm gold case for a superb aesthetic effect. The fact that the case is in condition nearly as perfect as the dial - with crisp hallmarks to the back, indicating a possibly unpolished watch - is the final touch for this remarkable timepiece.
