Hot Water: A Fix for Slow 32xx Movements?

[mrmahdi]

Greetings,

I have a Datejust 41 with the 3235 movement from 2019 that went to the RSC in Beverly Hills TWICE for accuracy issues. After a while, it was running within specs (still slow but within -2 seconds a day) and recently, it was running about 4-5 seconds a day.

I then read that running your watch under hot water can work because of the lubricants collecting in the movement, causing it slow down.

So I ran it under hot water under a sink, showered with it and put the watch in a bowl of hot water up to ten minutes.

It seems to have fixed it. It’s running again within specs or slightly out of spec at certain days but not the 4-5 seconds it was before.

So is the slowing of 32xx movements mainly due to the lubricants being used in the movements?
