I started a thread last week asking how I could prevent my minute hand from alternately lagging and overshooting the second hand. I spent a few weeks experimenting with different ways of adjusting the hands for alignment.

After every experiment failed, I finally called RSC today to arrange to send in my Sea Dweller for diagnosis. Tonight, I spent some time thinking of the results of the various experiments and thought I would try one last method. This is adapted from Bo's method of hand adjustment described in his FAQ. Thanks, Bo, for providing the fundamental clues to solving this problem!


It took a couple of tries, but incredibly, the minute hand now points precisely at the marker each time the second hand hits zero! The minute hand has gone more two round around the dial now, perfectly synchronised with the second hand.

I was almost ready to trash the Sea Dweller as the lack of synchronisation was really driving me crazy. Each time I looked at the SD's dial, I felt frustrated noticing how the minute hand could never get it right.

Now I feel so terribly pleased. It is like I've just received the SD for the very first time.

This is the method (notice it owes everything to Bo's procedure.)

1. When the second hand hits zero, pull out the crown to freeze it at that point.

2. Turn the minute hand clockwise 5 seconds ahead of the minute marker at which time will be set.

3. Notice the minute hand moves freely for about 2 mm when you adjust it, before it encounters resistance to the left and right. This free-play what Bo defines as the margin of "play" of the minute hand.

3. Slowly nudge the minute hand anti-clockwise until it points directly to the specific minute marker. The crucial trick here is to ensure there is absolutely no free play when you try to nudge the minute hand further clockwise. You should feel definite resistance. When there is the slightest free-play in the anti-clockwise direction, it will result in lagging and overshoot in the minute hand. All the free-play should be in the clock wise direction.

4. Push in the crown to synchronize the watch with your preferred time reference.

Those who have tried every alignment method in vain, I hope this method will work for you. I'll be monitoring the SD for a few days to ensure the alignment remains consistent.

It is just so essential and gratifying when the minute hand arrives at the appointed marker each time precisely when the second hand hits zero. It would not be a superlative chronometer otherwise!

That method has worked for me.
