1601 Datejust-concerns
Hello guys, I bought black bicolor 36mm Datejust 1601 from reputable seller, according to serial number they should be from 1977-78. I need your help if they are genuine. They should be sigma dial, but when I checked them with my Makro I-phone 13pro camera, the surface of dial looks pretty strange for me. I would like to ask you guys if the dial has not been repainted, if it’s original and sigma sign looks pretty strange for me because I already have champagne 34mm oyster perpetual with sigma dial and sign is better visible, but i do not know this is marked by gold pen. I would like to also know if these indexes existed at that time, because they are not usual and have not seen them.
Next think is that when I checked function for date change, it changed the date at 10:00 so watchmaker came to the shop and fixed it. Inhouse was 1560 caliber, but according my info they already should be 1570 after year 1972. They are also extremely inacurate. Let’s say -25sec per day. I need to say that they have hacking function and 1560 should not have this function. Currently they are fully wounded and stored. I am trying to figured out the reserve(if they have 42hours-1560caliper or 48hours-1570. Thank you very much for your answers. |

I think you will need to show photos, including of the numbers between the lugs, etc. Regarding the movement, plates and bridges were often exchanged, so I wouldn't worry too much about a bridge that says 1560.
