URWERK · UR-300 Time Quantum Titanium
Strengths
The transition between hours is the UR-300’s main attraction. That movement alone invites a closer look.
Things to consider
At 18.25 mm thick, fit needs a personal assessment; water resistance is limited to 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.
