Mentor Dress Watch

This watch has a Date complication and the dial is marked Shockprotected.  The 'T' on the bottom of the dial indicates that the luminencence was from Tritium rather the the more dangerous Radium. It also dates the watch as after 1968. Any luminescence would have faded and stopped during the 70s.
The Tritium paint compound would eventually be banned in 1998. 

Dial texture

The dial texture is a fine starburst that make light appear to radiate from the centre.  

Dial design

The dial shows the famous 1962 registered brand logo. The indices are sticks, or bars,  crossing over a golden circle that does around the dial. Technically it is actually a dodecagon rather than a circle.The golden dodecagon has a clever illusion of of appearing to be curved upwards for which the sticks would have to be raised but in reality whole dail design is completely flat. Although it all applied not printed. 
Each of the  indices has (what would have been) a luminescent dot. Even the date window has such a dot. The hour and minute hands also has (had) a strip of luminescent paint.
The twelve position has two sticks but only one lume dot.  

The case back

The case back gives us a little more information about the watch. It gives the model number 8272. What is says, going around the pentagon, is Antimagnetic - Swiss made - Diamond-tooled - Electronically tested


Movement - Baumgartner 866

The movement is a Baumgartner 866 (aka BFG866). This is pin lever movement with one jewel. That jewel is on the top pivot of the balance wheel. The jewel is held in place by a shock spring that absorbs any shocks or vibrations. Earlier watches without this 'shock protection' might snap the balance stem pivot if the watch was dropped or some other cause of impact. Thus the word "SHOCKPROTECTED" on the dial.
