The earlier Cvstos watches were not impressive, especially the entry level models. Not only were they aesthetically uninspiring, they were almost entirely based on various ETA calibres.
The new Concept S watches are a big step up; all the watches depicted are prototypes, you’ll note the caseback of the automatic is engraved “chronograph”.
They are well made, displaying a high level of construction and finish in the case and dial, as well as in the movements. Even if the movements are not wholly in-house, the watches are still impressive, especially the flyback chronograph.
Both the automatic and chronograph movements are based on the same base calibre as can be seen from the movement architecture, but the chronograph is integrated as a proper chronograph should be. Both movements have plasma finished bridges (plasma treatment is some sort of coating) in black; this look has been overused but it does match the aesthetic of the case and dial, and more importantly the overall finish of the movement is good, especially for this type of watch. Often brands neglect to finish a movement properly when they cover it in black PVD and often customers don’t notice. The movement can do without the meaningless engraving on the rotor though.
One shortcoming with the chronograph is the legibility of the subdials. The time is easy enough to read, but because there is so much visible from the front, it is difficult to focus on the subdials to read the elapsed time and the oddly shaped minute counter does not make it easier.
