Either that or the hour pinion is slipping due to an excess gap between movement and the underside of the dial, this is usually the cause when a washer is not used on a 2824 movement, this latter problem is not evident with a 2836.
If you don't mind shipping to me, and following my shipping instructions for outside EU shipping, then I can get it sorted for you. Drop me a pm, and I will forward my email etc.
Unless this, average watchmaker is experienced with reps, then it stands a good chance he/she won't be able to sort this out as you need an alignment tool for this job. One must also remove all glue from both date wheel, and date wheel overlay, etch both surfaces, and then refit with slow cure adhesive whilst aligning with said tool.
Rehaut is off slightly, possibly due to a misaligned dial, but this depends on the actual watch, if its a low end budget rep, then this is to be expected.
Love mine too, mine has genuine dial, gen hands, and get 1164 Omega Chronometer ETA 770 Also has a SunnyDale crystal, just looking out for a gen bracelet now.
Another vote for there carbon lens open, I have a set and they are great for removing blemishing in sapphires, plastic plexi's, if these are showing age/wear/scratches, the PolyWatch is recommended.
