The new 42 back and lugs are even. I’ll check the Perpetual Blue later today. The new 42 thickness is 13.8 mm. The full size Perpetual Blue IW503203 is 15.5 mm. The new Perpetual Blue IW503401 thickness is 14.9 mm. That may explain the appearance of the delta. My older Perpetual Blue is 15.5 mm vs 13.8 mm (Delta 1.7 mm).
The lugs on both watches are even with the backs. I can confirm the thickness of my Blue Perpetual IW503203 is 15.5 mm, the new Perpetual 42 thickness is 13.8 mm.
Beautiful watch. I understand that there is an interesting innovation with this new movement, i. e. one can adjust the calendar forward as well as backward? Is it correct?
Hi. The instructions I saw stated you cannot reverse the calendar. Also, as with most calendars, it has a "do not adjust" time window if you need to advance the date (around 2200h to 0200h - don't quote me). Excerpt from the manual: When crossing time zones in a westerly direction, you can set the hands of your watch back to the actual time of day. When doing this, however, you must not move back into the calendar’s auto- matic switching phase, i.e. beyond 2 a.m. If this situation occurs when you are travelling west, you should set the local time of your destination before 10 p.m. You must not turn the hands back between 10 p.m. and 2 a.m. This is because the calendar does not move backwards by 1 day when the hands are turned back beyond midnight, but remains on the same day. If you go past the end of the calendar’s switching phase (i.e. beyond 2 a.m.) when turning the hands back, you run the risk of the calendar advancing by 1 day for a second time and thus indicating 1 day too many.
