Hello from Singapore!
I currently own a 15500ST from APSF v2 and I have always dreaded the lume on rep watches. Is there any way to improve the lume duration or is it necessary for a GEN dial?
Also the rotor seems to be a little stiff for comfort and the watch does stop once 1.5 days after winding. Perhaps
@legend can help?
The gen APs are not known for lume. This is particularly true for the Royal Oaks, which feature very small and thin areas of lumed surfaces. If lume is your thing, a Panerai, or even a Rolex submariner would be a better choice. There is nothing wrong with the lume on the rep royal oaks.
Power reserve can be a tricky thing to discuss. It all depends on how much you wear the watch, and how you start it up. The 4302 is a relatively big caliber, and needs proper handling for optimal results. So what you do is:
- from rest (zero reserve), wind it up until the second hand starts to move. This can take many winds, as per gen. It is normal.
- then wind it 30 times more.
- wear the watch a full day and remember that wearing it alone does not give it enough reserve. The wrist has to move to cause rotor oscillation which in turn causes the watch to wind. If you wear the watch and sit like a statue for 24hrs for example, it is as good as not wearing it.
So wear the watch and ensure that your wrists have moderate movement throughout. Now if that condition is fulfilled, and you remove the watch and place it overnight for say 8-10hrs and finds that it has stopped in the morning, you can conclude that it does likely have a autowinding issue. Now if your wrist is not moving enough for it to gain power reserve more than it loses, then naturally it will stop after N days or hours. So you see, saying the power reserve has an issue is not a straightforward declaration which is always true. You need to consider how the watch is being started and worn. If you see that the rotor is stuck or not oscillating smoothly, yes it can be a visual cue that the autowinding to be inhibited or debilitated. In this case, the rotor bearing assembly will need to be cleaned and the rotor re-installed.
I am not saying that your watch has no issue. But you may wish to consider what I have written and then compare it to how your watch was handled. You may be able to say with more certainty if the autowinding/power reserve of the watch is problematic then. If it really does, it will require a service or movement overhaul. Either way, you do not have to worry. It is not a difficult issue to resolve.
