However, if you read further on, you'll note that I have been cautioning against use of Automatic watches during activities which generate a great deal of torque or inertia at the hands/wrist for years:

For automatics an additional concern to the above are activities that generate a great deal of torque or inertia at the wrist/hands... Activities such as Golf, Tennis, Polo, Baseball, Jai-Lai, Lacrosse, and the like are likely to cause the rotor to spin rapidly which is generally not a good idea... Sort of like running your car close to it's red-line at full throttle.

Many mechanical and automatic movement watches have endured long stints in extreme active use and survived no worse for wear. A number of movements are renowned for their toughness. These include the Omega c.321, c.861, Lemania c.1341 (Omega c.1040 and c.1041), c.5100 (Omega c.1045), Valjoux c.72 and c.7750, movements. There are probably others. In all instances in these cases the watches in question were: quality made, robust movements (not a lot of delicate complications), and in good mechanical condition and well serviced.

However, it is not advisable to wear an automatic for the "high torque" activities mentioned above, a more robust manual wind or a quartz would be better choices. I would be more concerned about wearing an Automatic watch when shooting than I would be a manual wind, not only because of the rotor but also because there is more to go wrong typically.

Thus, a 7750 based automatic watch would not be my first, second or third choice on the links. But do as you see fit.
