ochs und junior · settimana raw 40 mm
Strengths
The appeal is clarity of thought rather than a parts count. A dot replaces the weekday label, but resetting after a stop requires patience.
Things to consider
There is no independent quick weekday correction: the manual calls for advancing the time. The brand’s page does not specify this version’s exact reserve.
IWC · Big Pilot’s Watch Perpetual Calendar TOP GUN Edition Mojave Desert
Strengths
The strongest attraction is the complex calendar paired with a matte desert palette. For a lover of large mechanical watches, 46.5 mm gives the displays room, but demands a suitable wrist.
Things to consider
Try it on before buying: the case measures 46.5 × 15.5 mm. Confirm the movement in the actual example; the original announcement and current IWC listing differ.
