My holy grail - Seiko Big Electromechanical Flip Clock

[hank7444]

I got this one and fortunately it runs well after a clockmaker oiled it!

The inside is really complicated but I really love it.

I believe that it was made in 1960s,
Its weight is 5 kg (11 lb) because it's almost made of metal

An absolute gem of a clock. Really nice find.

[hank7444]

Thanks! I will try my best to take good care of it!

[Mackey]

I really love that! thanks for showing!!

[Johan de Jong]

Congratulations! That is a beautiful and very well built clock.

[hank7444]

Thank you!

I try to find more information about this clock, but there is really too little information on the Internet, sad

[hank7444]

So exciting! I found that it has a perpetual calendar function,
let me verify next month is it can correctly transition from April 30th to May 1st

Oh my! What a find! Truly mechanical flip clocks not powered by electric motors are rare indeed. Glad it ended up in someone's hands to take care of it!

This really is a Solari style clock. I wonder if they copied the mechanical part or if they designed their own. It would be interesting to see them next to each other.

I would love to own a Solari Cifra 5 one day, but will have to save up for a good one

[hank7444]

I guess they must have a reference to solari's structure, and add their own creativity.
by the way, the mechanical flip clock I only saw it on the early production of solari , the later production has not adopted this design

This SEIKO flipclock is really cool and also very rare.

[hank7444]

Yes, it is my diamond!

I tried to find a MSD-991 before, but failed.

The largest SEIKO flip clock on my hand is here. It is a slave clock.

I have another 4 big CITIZEN flip clock. They are also slave clocks.

[hank7444]

Wow, nice collection! By the way, I'm also from Taiwan

[eathan21th]

Thanks. I knew that you are also from Taiwan. I saw your post on PTT as well. Btw, this clock is restored by Kolock, right ?

[hank7444]

Yes, the watchmaker just oil it and adjust some part, it has no any big issues

[azar42]

Wow, this is an absolute beauty (and an absolute unit!) I love it. hank7444, can you share a bit about how you found it? Any tips on how/where to track one down?

[flipoclock]

Your best shot would be in Japan, using www.buyee.jp I buy a lot of flip clocks there. You will have to be patient and factor in high shipping and possible import duties depending on your home country.

[azar42]

Thanks I've been looking on Y! Auctions already, so I'll probably just make it a daily thing and hope I get lucky.

[hank7444]

azar42 I found it in a small antique store in Japan, I don't mind if I have to make a big space for it in my luggage

[azar42]

Just saw this response, and wish I'd seen it sooner! Sent you a PM
