Introducing: The Grand Seiko 60th Anniversary Restricted Version SLGH002, With New Hello-Beat Escapement Caliber 9SA5

The stability, faraway from the motion, has a number of tales to inform. The primary of those is the stability spring – it is an overcoil kind, which signifies that there isn’t any want for a regulating index; that is traditionally a function of higher-end actions oriented in the direction of precision timekeeping. With out an index for regulating the watch, timing weights on the stability are vital – that is the primary time I can recall seeing them on any Grand Seiko watch, the place flat stability springs and traditional regulators have been the rule previously. Rolex makes use of an analogous strategy within the type of its Microstella stability screws and Patek, after all, has its Gyromax balances. Omega makes use of flat silicon stability springs that are fabricated in such a means as to offer the benefits of an alloy overcoil stability spring, and like Rolex, Patek, and now Grand Seiko, additionally avoids a traditional regulating system by utilizing timing weights on the stability.
