Sea-Gull proprietary flying wheel is located at 6. Sea-Gull researched and
developed this type of “poor men’s tourbillon” flying wheel. According to
Sea-Gull’s educational advertisement, mounted on the central axis is a flying
wheel that has higher mass thus higher inertia. When the machine is running at
higher speed, the flying wheel’s kinetic energy increases, absorbing and
storing energy; when the machine is running at lower speed, the flying wheel’s
kinetic energy decreases, releasing and distributing energy. Thus the flying
wheel plays a role to stabilize the pace in the operating process.
Sporty looking M307S, relatively large – 42mm in diameter, 14mm

Another point worth mentioning is the month does Not move forward by itself after 31 days. If it did it would
be perpetual calendar movement costing much more. The month calendar has to be adjusted by pushing the recessed button on the left side once each month.
