1937 was one of those revolutionary years in Omega when they introduced their first watch with a centre sweep seconds hand. Prior to this, the seconds hand was always in a small subsidiary dial which was more an indication of seconds and difficult to read with any accuracy. Whilst in most situations this was fine there were some who actually needed the practicality of easy reading. Known as the Medicus this watch was perfect for a doctor to use as part of the procedure to accurately measure a patient's pulse.
 
Back in the 1930s men's watches were much smaller than today and the Medicus was no exception with a typical diameter of 30/31mm. A very small percentage were produced as jumbos and this example at about 35mm is a great example. The later 1950s classical Seamasters rarely exceeded this size so it clearly has wrist presence even by today's standards. See the picture comparing this to a 34mm Seamaster.
 
So, a 35mm stainless steel case (excluding the crown) in good condition, free of dints and major scratches. Of course, there are signs of use however this manifests itself mainly by the gentle rounding of its edges. The magnificent big wheel semi-concealed crown is original and works just as it should; far easier to manipulate than the tiny fiddly concealed crowns on the later Constellations. The snap-fit case back is also in good condition.
 
The dial has been refurbished in the style of the original. A technical dial with its railroad minute index further sub-divided into fifths. All original blued steel diamond-shaped hour and minute hands beautifully complement the large dial. Anything smaller would have looked lost and unbalanced. Infilled with contrasting luminous material as are the black printed Arabic numerals. Full length blued steel sweep seconds and with a small counterbalance on the end typical of the Medicus range. Signed Omega.
 
Inside the case is the Omega 23.4 SC calibre movement. The 23.4 range ran until 1959 and a total of only 120,100 movements were manufactured. As can be seen it's in exceptionally good condition and sits well inside the lager case that was designed specifically so the movement would fit snugly without the need of any type of filler. The serial number signifies the watch was manufactured no later than 1938. Fully serviced.
 
Comes fitted with a used NATO style strap from Italy.
