Whilst recently rummaging (very carefully) through the safety deposit box, I decided to strap on my UN Perpetual Ludwig GMT +/- Ltd. Ed. in Pt. for the first time in a while only to find that … Alas! – it’s apparently been TOO long of a while. Appearing a...  

1 - Safes in banks (or anywhere) are actually quite humid and even if not felt should be considered as such... I recommend maybe a silica gel sachets, which if nt very useful, are not harmful at least ! 2 - Regarding the patina of your Type XX, I have rea... 

Thank you, Montres1, for your insights and recommendations… I’d previously given thought to silica gel sachets, but didn’t deploy them out of (misplaced) concerns about drying out lubrication. Very interesting that a drawer’s darkness can accelerate patin... 

Perhaps the lubricants used in the watch soaked into the dial and caused the discoloration? It may show more on this watch compared to others because of the light colored dial? Just a guess...

I’m assuming that the metallic dial (I’m not sure of its composition) isn’t porous, but thank you for your helpful conjectures, JG.

especially after many years with no service, i.e. the same (old) seals. Do you measure the humidity? It should be between 40-60% - everything outside this range could be a disadvantage for the longlivity of a watch, dial etc. and yes, it seems to be a sil... 

Thank you, Markus. Mea cupla. Years of no service, no measuring of actual humidity. I apologize to my poor Ludwig.

Thank you guys, for your input.

I hope there is a solution for you. It happen, so focus to another mindset. Yes, i use some silica bags in my watchbox and i rotate my watches. ...  

Thank you Weems. I’ll plan to focus on another mindset (as my wife recommends this anyway : )

Once I bought old NOS IWC Ingeniour once which was sitting in the retired watch dealer safe for decades. First time we took it out of the safe the dial was white, but after a day in the sunlight it turned yellowish. The dealer explained to me that is how ... 

Thank you, MrkK for the interesting Ingenieur anecdote and sanguine news about UN's spare dials w/ empty cartouches!

No explanation. Maybe we all should check all watches locked away.

Yes, indeed, I’ve begun checking my other watches, too.

Banks do shut off air conditioning at night, and the humidity does rise a bit. It's highly likely that your contents saw some humidity and temperature variation. Because banks close all of Sunday, from Saturday close till Monday morning open, the bank has... 

Do you ever seen it? I can little remember when i read a manual, it can be also a power tool or tv. A product can have this, usable at minus 5 degree Celsius to let’s say 45 degree Celsius. But a manual, and it can be with watches that the best habitat is...

Returning tardily to this thread... please excuse my late thanks and acknowledgment. I'll check on Amazon, sounds like a good deal for a useful instrument!

Good luck!
