1982 Tudor Advisor Alarm (Ref. 10050)

There was a time when alarm watches were the most functional complication a watch could have. Released in 1957, the Ref. 7926 was the first Tudor Advisor. Whilst the Cricket and Memovox used a case with two backs to amplify sound, the Advisor used an adapted Rolex Oyster case. Unusually for an Oyster case, neither of the crowns are signed with the iconic Rolex coronet. If the crowns are original, then both will be unsigned. The top crown wound, set and activated the alarm and the bottom crown wound the main movement and set the time.  

In 1969 Tudor released the Ref. 10050, the successor to the previous two Advisor references. Instead of the Oyster case, a more 'traditional' alarm case was used with an external case back that increased the volume of the alarm. The lugs of the watch were different as well although both crowns were still unsigned. Stick hands replaced the older dauphine hands and the new Tudor shield logo replaced the rose at 12 o'clock position on the dial. The Caliber AS1475 was also replaced with the Caliber 3745.
