A few of mine: 1- Hamilton model XXI marine chronometer. 2- Speedmaster, sapphire back, 1989, anniversary of Apollo XI moon landing. 3- Hamilton 952, 19-jewel version of the venerable 23-jewel Hamilton 950. 4- E. Howard Watch Co., series VII, CIRCA 1884. 5- Louis Brandt (Omega) model CCR, 19-jewels, circa 1910. 6- Keystone Howard model XI, railroad chronometer, based on a New York Standard model movement. 7- Rolex Prince Observatory duo-dial, 18-jewel chronometer, circa 1930. Movement also used by Gruen. Made by the Swiss firm Aegler for both companies. 8- Rolex caliber 700, also used in Gruen, circa 1935. Made by the Swiss firm Aegler for both companies.
The 950 and 952 came in three versions over time. Your 950 is a later version, compared to my 952. Mine was the first version, and has a four footed dial, a one piece barrel arbor bridge, and two screws holding the crown wheel. Yours is the third version, and has a three footed dial, a two piece barrel bridge, and one screw holding the crown wheel. Then of course there was the 950E and 950B, two even later versions of yours. I have a 950B, but it is not as pretty as yours.
In general, I think the mechanical hand-winds are the most beautiful movements... there's no rotor to obstruct the view! One of my favorite movements, the Longines 30LS:
Not to say an auto can't be beautiful, too. Here's my Constellation's cal 551 that's a very early serial 17 million that is one of the 'famous 20,000', a series of 20,000 movements that achieved especially good results in official chronometre testing of 1959: (photo credit goes to @cristos71 )
