Mechanism: The Rolex 710 is also known as the Gruen 827 and was in fact made by Aegler (as were all Rolex movements prior to 2004). It is one of the many movements derived from the Hunter 10 1/2. This is the 17 jewel version. Main spring: 1,50 X 8 - 0,09 - 270. Manual wind, screw balance or super balance.

The 710 is closely related to the Aegler 700. The primary difference is the position of the second hand. The 700 is "sub second", whereas the 710 is "center second".
