I’m not familiar with this front loader but was drawn to its unique maroon colored dial. I’m not sure what movement it contains. The crown only has only one position: time set. Anyone familiar with this version of Admiral and how to set its day/date?

 

As I remember the date is quick-set by pushing the crown.

 

When servicing this watch my watchmaker noticed the markings "D11KAS-2" and "1958-2" on the movement which is a Wittnauer reference. My understanding is that this equivalent to Longines 503. However, does this imply that the previous owner replaced the original Longines movement with a Wittnauer? I know the two companies were affiliated at one point.

 

Was the movement signed Longines? Or unsigned and just with those markings?

 

May not have a quick set day. You may have to cycle the days using the time setting position.

 

It does have a quickset date when you push the crown.

 

But the day may not be quick-set. Here is the Ranfft database page for this series of movements. Some have quickset date, but none appear to have quickset day.

I don't know if it signed Longines. I know is it's marked D11KAS-2 and thus am concerned if it's the watch's original movement. I know a Longines movement would be marked 503. I am awaiting a photo of the movement. I'd like to know if anyone can confirm whether this is the watch's original movement based on the D11KAS-2 marker.

 

The reason I asked is that there is a third possibility which is that the original Longines movement has been repaired with replacement parts from a different movement (or movements), i.e. Wittnauer and/or Record. I think it's best to show actual photos instead of speculating based on second hand information from the watchmaker.

 

I am not necessarily speaking about this one in particular. But I run into these day date models which require you to advance the hands until the correct DAY shows. STOP! Back up the hands until the previous day shows STOP! Advance the hands until both day and date change. STOP! Back up to the previous day, the date doesn’t back up. In other words, the DAY will back up, but the DATE won’t. So it is back and forth until you have the correct DAY and DATE. Then set the watch to time.

 

Original post edited. Pulling crown out from neutral sets the time and pressing crown toward case from neutral advances the date. I assume the day needs to adjusted by advancing the time.
