Chopard · L.U.C 1860
Strengths
An elegant addition for a collection seeking slim Swiss mechanics: hand-guilloché and a micro-rotor provide substance without calendar complications.
Things to consider
Try the 36.5 mm case: it may feel too small to a large-watch enthusiast. There is no date, and water resistance is 30 metres.
Bianchet · Tonneau UltraFino Black Ceramic
Strengths
The successful detail is the scale of the gold accent: one fine line ties the composition together.
Things to consider
Ceramic needs protection from sharp impacts; a movement’s quoted shock resistance does not make the case invulnerable.
