Patek Philippe's five "Comets"
In 1942 and 1943, Patek Philippe released a set of five different watches powered by the same caliber 10-110 and sharing a design centred on rounded shape and elements (multiple dot indexes on the dial & rounded outgrowth on the case).
Because of these rounded elements placed in some kind of orbit around the central pinion, this quintet of watches has been nicknamed "The Comets" (it seems to me that "The Satellites" would have been a little more appropriate, but who cares).
Art deco? Steampunk? It's hard to tell how this style should be described, but it sure is extravagant, daring and futuristic.
Best to you all!
Ref. 1540 (dot markers for the minutes, hours and every fives seconds + four rounded outgrowth at 3, 6, 9 & 12)
