Broken crown on the 15202 Jumbo!!

From a winding/date perspective I have always found that the crown is particularly small and difficult to wind and even more so to change the non-quickset date. A few years back I was touring the AP factory and noticed a winding tool on the bench of a watch maker who was working on the 2121 (Jumbo) movement. When I got back home I asked my AD if they could source one of these tools as it would likely make the date changing process much easier. A week later they called and asked that I come in. Not only did they have the tool but it was a much more deluxe version that I had seen at the factory. A few pictures below - this thing has been a life saver.

That’s really cool! So one side is for turning the crown and the other is for watches with pushers I assume?

Yes, that’s correct. Inside the leather case are different tips that fit the various AP cowns. Pretty cool little tool and a godsend for those date changes.

on that note, it would make sense to produce Jumbo with no date

I seem to have seen this happening frequently with some here on the forum. Can anyone share their experience with this? Was it covered by warranty? Did they have to send it back to Switzerland for repair and, if so, how long was the turnaround?

I am a little upset about the timing with the summer heat rolling around as it is usually my go-to watch with a suit during the summer.

I will take it to the boutique in Tokyo tomorrow to see what they say.

The Achilles heel of the calibre 2121.

Is a know issue since 1972 with calibre 2121. Because of its thinness the way the crown engages makes it prone to it.

I wore a RO Jumbo Perpetual for years and no issues with the crown. But it is delicate compared to many watches. A sporty, not a sports watch. In the end I traded it for a platinum Day Date 40 which can take a beating better.

Sorry for bumping up an old thread but does anyone know what's the size of crown on 15202? I cant seem to find the winding tool from AP so thinking to buy third party tool but havent' measured the size of crown in mm.

Does anyone know please?

it depends on when you bought the 15202. The later model 2019 or newer has a bigger crown so it's easier to pull the crown without pulling it too hard.

Are you sure this is true? I have never heard this before or noticed based on pictures comparing my 2020 15202 to earlier versions / the 5402. Looks to be the same size.

[OH2004]

This is what I've heard. Mine, which is fairly new doesn't have the crown issue when I set the date and time.

I too had difficulty turning the crown and look for solutions ( i was looking @ non-OEM as AP said it will take months) Called Clearwater Service center FL and they put me in the waiting list for the tool (actually ordered one for me from Sweden). Took ~ 2 weeks and $170?? .

This is what i use as well

Up on reading others they claim damaging crown using non-OEM. Was willing to wait for OEM tool. highly recommend to others.

Don't forget: you all appreciate having one of the most outstanding pieces of watchmaking carrying one of the thinnest movements in history. So it's no surprise that these pieces are a little more delicate if used as a daily wearer although they are perfectly apt to that.
There's a tiny little screw holdingvthe crown inside. If it comes loose, the crown comes off. In a more robust movement the screw is bigger and does not become loose as easily.

I had the same issue with mine a couple of months ago and had to send it to clearwater for service and they didnt even mentioned about the detached crown so I think this is somewhat of a common issue.
I have also an ROC but the 15202 is much more delicate and now Im very careful when pulling the crown.

4.5 mm

I just use a piece of rubber surgical tubing which just fits over the crown and can be used to either wind or with a little pinch allow it to be pulled up for date setting.
