I see no upside to leaving the crown out, but several potential downsides (already stated by others). Leave it in it's normal secured position.

If it’s a super humid place where you live, maybe put it in a baggy with the crown out and a few silica packets for a couple days, take it out and screw it back down, put in storage. Couldn’t hurt.

Crown in. There's a reason it's called position zero. It is the position it is meant to be in unless utilizing a setting function. If it hacks and uses a brake, you are also just leaving it set on the brake.

With my non-hacking watch, I know it doesn't matter - it'll "run" whenever it gets energized, but with a couple of my hacking watches - their rotor is sensitive enough that if I start transporting them they'll run.

I didn't know if it's better to just leave the crowns open and in 3rd position (hacked/time setting) so that the movement never starts running (if it gets shaken, or turned, etc.). Also, would that allow moisture to get in/out of the movement?

Depending on how much jostling you're doing when you move your watches around, it'll run for a few minutes to perhaps hours. But that's still very little if you're not going to be wearing your watches for months at a time. Really, how often would you be moving your watch collection around?

But leave the crown in. I'd be less concerned about water (I'll assume you're not leaving your watch collection by the side of a sink or pool - so how is it ever going to get wet?) but an open crown isn't as protected or secure than one that's closed. Especially if you're worried about carrying it around - just keep the crown pushed all the way in.

I'm suprised nobody said they store the watch in dry argon or freon. Inert gas. Crown open. Temperature fluctuation causes the watch to 'breathe'. Moisture!

Lol, just kidding. Crown closed. Kept out in the open on my dresser. Life's too short to keep filling up a container with argon. The wife will kick my rear if I use up all of her computer duster.

I don't understand why you would ever leave the crown out on an automatic?

As mentioned, the risk of damage at some point and the possibility of dust or debris entering the case, (not likely if in a watch box/case but still.....) or dust/debris settling on the crown threads.

I can't find any upside to it.

Crown in. Always.

 

[NC_Hager626]

Crown in to prevent the entry of dust particles.

 

[Bird-Dog]

OMG! You worry about wear on the mechanism if left on a winder, but are considering storing your watches with the delicate mainsprings under tension for months at a time?

*I don't actually think that's much of an issue. It's just kinda' fun to see people overly concerned with trivial details go into panic mode hearing something that sounds like a potential problem, even if it isn't.

 

[teckel12]

Closed, why would you ever leave a watch with the crown out?

Kinda like leaving you car in the car park with the bonnet up.

Exactly! My OCD is at 11 just thinking about this.

 

[Awax]

If you're afraid of moisture getting into the watch, you can always store it with one of these silica packs you always find in shoeboxes ...

 

[Rastafadda420]

So, a rather silly question: Should I store my watches in a case with their crown in, or crown out/open?

I know I could put them on a winder, but I know I'm likely not going to wear them for a couple months, and don't want them running and wearing their parts down in the meantime.

With my non-hacking watch, I know it doesn't matter - it'll "run" whenever it gets energized, but with a couple of my hacking watches - their rotor is sensitive enough that if I start transporting them they'll run.

I didn't know if it's better to just leave the crowns open and in 3rd position (hacked/time setting) so that the movement never starts running (if it gets shaken, or turned, etc.). Also, would that allow moisture to get in/out of the movement?

Or is this a case of me being anal retentive and it doesn't really make much of a difference at all.

Thoughts?

I don't think it matters.

 

[MissileExpert]

How was it shipped to you? Probably with the crown in. That's all you need to know. It's not like a quartz watch where pulling the crown stops the movement, therefore not drawing any battery power.

 

[slorollin]

They're stored crown in, but not because of science, religion or superstition. That just the way they are when they come off my wrist.

 

[Rolexplorer]

I leave the crown screwed in on my watches when stored. I do try to give my automatic watches a good shake or Two to get them running or movement running for a little while, about once a month . I even run the Chrono, just to keep everything working. Vance.

I like this post, vmgotit's advice in post #18.

Original Poster:
Not a silly question at all.
If you live in a very humid climate, I would definitely keep the crown closed.
For long term, I would always keep the crown closed, whether it is a water-resistant watch or not.
It is always best to choose the path of least potential ingress of dust and moisture to the movement.
If your stem and tube system is worn, such as on a possibly older watch, dust and water can have an easy path into the case.

 

[fjblair]

I keep them closed, but it doesn't matter assuming they are encased.

 

[jenyang]

Crown in - if it's out, you also risk dust, no matter how minimal getting in or on the threads.

Right, and possible moisture.
