This is the Hi-Beat beast that showed the horological world what the Japanese were capable of! The Seiko calibre 4522A has a rate of 36.000 bph, thats 10 beats per second, a frequency of 5hertz. This watch is in very good condition, but in need of a routine service.

A lovely piece of work as always. Do the vintage hi beat GS movements you have worked on suffer from the additional abrasion that seems to afflict some Zenith watches which also run at 36,000?
No I usually don’t see the same kind of aberration. On the Zenith it might be related to the power of the mainspring and the autowinder mechanism.
Thank you – that is interesting.
I am now the lucky owner of this watch! It is quite stunning in the flesh and one of my vintage watches which I am likely to wear quite frequently. It has been a pleasure dealing with Mitka on this purchase – he has previously worked / serviced a number of my watches. Always a delight to deal with, I can sincerely and genuinely recommend his services to anyone needing their watch repaired or his workmanship on the watches he has repaired and for sale here.
