After a long period of not wearing my Croton Hourmatic, I've recently had it in for service and am putting some time on it. It's a fun little triple date bumper automatic. It had gotten so dirty that it stopped one night when rolling over to the next day. A trip to my local watchmaker now has it keeping super good time (I REALLY like that guy!). However, I noticed last week that the day of the week and day of the month rolled over, but the month did not change. I can't recall if it did before, and don't want to take it back to my repair guy if it's doing what it's supposed to. The movement is stamped Croton, but best I can tell it's an AS1315 (search the Ranfft pages, I'm new enough I can't post a link). Can anyone confirm whether the month SHOULD advance, or is that manual advance only? I've read that some of the old triple dates didn't move the month themselves, and I just can't remember whether this one did before the service or not.
