from Hodinkee:
Key details like the placement of subdials, calendar apertures, and
tachymeter all remain the same. One of the more notable updates
is to the case size: at 42mm, the new model is substantially larger
than its more modestly-sized predecessor, which clocked in at 38mm.
Viewable through a sapphire case back, the Calibre 410 runs
at 5 Hz with 390 components powering three distinct functions
in addition to basic time keeping. The aforementioned
column-wheel chronograph function uses two subdials, a 30-minute
register at 3 o’clock as well as a 12-hour register at 6 o’clock.
A sub-seconds dial sits at 9 o’clock as well.
The calendar function includes day, month, and date. The day aperture
is placed at 10 o’clock, the month at 2 o’clock, and the date between
4 and 5 o’clock. Having the calendar apertures spread out in this
way does detract a bit from the overall readability of the dial.
