Seiko Majesta
cal. 5S42
Factory Spec. 20 SPY
HAQ method unknown
User Adjustable: No
This unusual watch employs the high-accuracy version of Seiko's 5S calibre. The second hand appears to glide smoothly around the dial, as the stepper motor delivers four pulses per second through a viscous dampening mechanism that eliminates the classic 'tick'. Unlike its sibling 5S21 calibre, hacking the 5S42 does not cause energy to bulid up in the mechanism and consequently allows for normal time-setting operation.
UPDATE - I have sold this watch. Rather unfortunate that I managed only to sell it for parts, as it was in good, functioning condtion. Still, that's life.
Some details for this watch are missing because it did not undergo comprehensive testing.
