Storing a GMT Master?

[WHUFC]

Hello
I have a GMT Master from 1987 that I want to give to my son for his 21st birthday, (he is 9 at the moment) as it was my 21st present from my parents. I have stopped wearing it and at present it is on my watch winder. Would I be better to just put it away in it's box until the time of leave it there? I would prefer to put it away as it using a slot on the winder and I will be replacing it with a Sea Dweller when I find the right one.

I will happily 'store' it for you. No charge necessary for this service

If it helps solve the problem I don't mind giving it some wrist time a few times each week for the next 12 years.

You can thank me later

I am touched by your generousity, it must be the christmas season!

I'd let it run down and store it in it's original box until a few months before the time comes to pass it on and then get it serviced. Keeping it in use will mean wear to the movement and so servicing regularly.
