Misalignment of date disk

 

Marcus, thank you for your detailed answer.

I'm aware that I cannot expect a "perfect" alignment of the calendar indications. However, I also own a simple GMT +/- and the alignment of the this big date indication is much better than for my perpetual.

The alignment on the perpetual does not change after manual setting of the date forward and backwards and subsequent automatic date change. The slight inclination of the numerals on the inner disk remains unchanged regardless of whether the first figure of the date is 0, 1, 2 or 3. Therefore I suspect that the inner date disk might not perfectly be adjusted on the shaft of the pinion.

Maybe I'll take some more pics and send them to UN and ask for their opinion as I agree that we are talking aboaut a borderline case. Do you have any hint for me whom I should contact at Le Locle?

It would most definitely bother me. I would not hesitate to send it back. What good is having a highly valued timepiece if the only thing you are going to focus on every time you look at it is the poorly aligned date wheel. It would be much better to spen...

irony aside, it is really true: The big advantage and most unique feature of UN's big date - and perpetual mechanism -, that it can be set both forward AND backward, also is responsible for an increased chance of misalignment in the indications. All conve...

I had the same problem with the San Marco GMT and the GMT Perpetual, the latter was serviced in Weil am Rhein and it was a complete disaster. The perpetual was finally fixed in Le Locle, the San Marco GMT was serviced in Le Locle and looked awry after I c...
