Are vintage oyster cases waterproof?

Hi,

I would love to get a waterproof vintage watch to use when I'm out on the boat or swimming. Currently I'm using a Seiko diver, but not really happy with it since it can't be manually wound, looks too contemporary and I'm not really feeling the diver aspect either.

So maybe an old Tudor in an Oyster case would be good. Would love to know if these are actually waterproof enough that you can swim and surface dive with them?

Is there anything else I should take into account when buying a vintage Tudor? I would like the watch to be affordable, simple to service and keeping reasonable time. Would this mean a manually wound movement would be my best bet? Something like this: http://www.ebay.com/itm/262824656514?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT

I thank you for your advice!

Stick with your Seiko! Water resistance only happens if a watch is maintained to be water resistant. And on a lot of vintage Rolex watches, they are likely the only source for parts, and I understand they consider a lot of vintage watches as obsolete and won't service them! I have 5 Rolex Oyster watches, and none of them go anywhere near water!

They were when they were new 50 or 60 years ago. However, the water resistance is only as good as the weakest link. Generally, that is going to be the case or crown seals. Replacing these may help the watch pass a water resistance test, but remember that it's only as of a point in time.

Since many of the parts inside the watch will be difficult, if not impossible to replace, you are taking a very big chance by letting it anywhere near water, especially salt water. The effects of soap may be even worse, as it has molecules smaller than that of water that can slip though even a water resistance seal.

In short, this is not a good idea. Go get a Casio G shock for use when diving and save the Tudor for when you're having a beer after the dive.

Could you make a true vintage watch waterproof/resistant? Probably. However the general consensus is not to mix vintage with water - If properly serviced I would only trust waterproofing to exposing the watch to hand-washing and under light rain, I would not venture with it for swimming/surface diving.

Why would you use anything but a diver when swimming and working on a boat? Look even vintage submariner guys don't take theirs swimming and they are more water resistant then a regular oyster.

Honestly lack of manual wind on the Seiko does not bother me. All of mine from vintage to modern basically start right up when I pick them up. The magic lever winding system is one of the best automatic systems out there.

I would take a Picasso on a boat. I just wouldn't go swimming with it.

Have you considered a modern classic from say, 1980s or 1990s? Instead of a vintage? Less fragile. Less pricey. Easier to maintain water proofing.

No. And probably not retail. Ask a respected seller on TRF or VRF about what you might be looking for. Also you didn't mention budget? Don't expect to find a Rolex or Tudor in the same bracket as Seiko.
Don't have a firm budget, but I'll probably stick with my Seiko if I don't find anything for less than thousand euros. A big reason for asking about vintage Oyster cases was that it seemed to me that manually wound Tudors could be had for about that.
