Deep Sea Dweller Reserve Issue?

[johnk]

I had my DSD serviced by the Dallas RSC a few months ago, excellent experience. When winding and setting the watch a month or so ago, something felt odd and it took several attempts to get the stem in the correct “setting” or “wind” position before I could turn the hands or wind.

I’ve noticed recently that the watch is always dead every other day. I wind it 40+ full turns, wear it actively ~4 hours each day, and every other day it stops, as though it’s not self winding and running off its reserve time. I’ve owned dozens over the years and presently have 8 Rolex Sports watches.

This one is my daily driver, and gets more wrist time than the others. I realize it’s not an exact science, but I’ve never experienced this issue before.

Simply a function of not enough wrist time to self wind? I’ve had others before this DSD in daily wear rotation that have gone weeks before I stopped wearing them enough to self wind.

I’ll test it the next time it stops, fully wind, wear, note the wear hours and the exact time it stops to see whether it’s consistent with the watches reserve time..

Thanks.

Hi John,

The full wind and 4 hours worn will not give you an accurate run time for the PR.

Just give it a full wind and leave it unworn for the PR value.

Isn't the reserve calculated at full manual wind?

I'm fully winding it, wearing it directly 4-5 hours after a full wind, then wearing 4-5 starting about the same time the next day. By hour ~48-50 on the 3rd day, dead.........

Is 40+ full turns enough for the DSD? It's certainly enough for my other Sea Dwellers. I don't recall having this issue before the DSD service and the 'odd' time pulling the crown out multiple clicks didn't appear to do anything for a while..

No.
The power reserve is a function of the state of wind/status of power wound into the mainspring, whether it's been manually wound(fully or partially) and the same applies to on the wrist.
As the watch has been serviced by Rolex. I would safely assume it's functioning correctly so there is another variable which needs to be pinned down or identified. Introducing a manual wind proceedure is potentially counter productive unless one thinks the outright power reserve is somehow not up to specs.

Personally.
I can wear mine for an hour and it will run for 6 hours on a reasonably casual day in my life. It's effectively a 1:6 rario.
Try coming at it from another angle.
Wait until the watch has stopped and simply put it on and wear it just as you normally would for 3 or 4 hours.
Record the amount of time it runs after you take it off, and you will have a baseline of how much power reserve you are winding into it. Do it a few times just for fun and you will be able to establish a trend in the numbers that you can go forward with and reach a conclusion that's plausible.
Please let us know how you go with it?

I had this happened to my SeaDweller 16600. Full wind then wear everyday actively 8 hours by the start of 3rd day it stopped. I was actively travelling for work so i wasnt sitting in front of the computer all day.

Puzzled i did the following:
To test if there is a problem with the power reserve, i Full wind it and left it untouch and see how long it runs for. Turns out my power reserve was up to spec. So i began to suspect my winding mechanism is at fault.

Gave it to my local watchmaker to have a look. It turns out my winding rotor wasnt spinning because one of the screw that holds the "bridge retainer" was loose and stopping the rotor from spinning.

no one asked what movement his ref DS has? 31 or 32 ? big dif in reserve power between the two
