​How to better determine if a datewheel is centered.

You need to use the cyclops and date window framing relationship. Only when the date window is perfectly framed (top, bottom, left, right) by the cyclops will the true picture of the datewheel / date window relationship be revealed. If the cyclops frame on the date window appears wide (thicker) on one edge (top, bottom, left, right), it will push the apparent position of the datewheel to the opposite side of the date window.

If the cyclops appears wider on the right, a properly centered datewheel will look left justified.

If the cyclops appears wider on the left, a properly centered datewheel will look right justified.

If the cyclops appears wider on the top, a properly centered datewheel will look bottom justified.

If the cyclops appears wider on the bottom, a properly centered datewheel will look top justified.

Only when the date window is perfectly framed by the cyclops will you be able to assess the true position of the datewheel relative to the date window.

Look at the pics below of my gen GMT to see how a wide cyclops on the right edge pushes the appearance of the datewheel to the left side of the date window. In the second pic the date window is better framed by the cyclops and the true position of the datewheel can be seen.

How to properly center the DW and/or DWO if it is a bit off ? It’s apparently a very common phenomenon for nowadays rep

DW positions on true clones (3xxx) cannot be altered. If they are off you need to try a new DW. It is possible to clip dial feet, rotate the dial slightly, epoxy it on, etc. But this can easily snowball into a headache due to rehaut alignment and cyclops position. Only time this is really a useful option is early in a build like before the hands and the crystal retaining ring are on.

DWOs can be adjusted infinitely in all axes - that's what makes them so much fun to apply. I discuss how to do this in great detail in the threads below. Apply slow cure epoxy then nudge, rotate and check every number. Fixing one will throw off another. 31 perfect positions can require a dozen or more adjustments, hence the fun. NOT!

Gen or gen-spec DW as a DWO
