Hey! How's That Work? | Grand Seiko Spring Drive | Crown & Caliber

Grand Seiko's Spring Drive movement is pretty close to magical. Luca (Actual Watch Technician) walks you through just how this mechanical marvel works.

Spring drive movement is the most beautiful thing ever. Owning a GS someday is on my bucket list.

Crown and Caliber is becoming one of my favorite channels. Great video.

This movement is pure genius! I love the spring drive. Mine is running 1-2 sec per month!

Nice job Luka! No snobbery, just simple and clear information.

[WilsonLee]

This was very fascinating! Grand Seiko makes some beautiful watches.

[gerardanthony]

Delightfully informative and watchable. Several times! Thanks!

[estoyconfused]

Thanks, Luca! Lol Do a tourbillon next please!

[paolocacciatore]

Really a beautiful video. Only one thing I would say is that quartz does not always oscillate at 32768Hz. Its frequency depends on its physical dimensions, the higher the dimensions the lower the frequency, and this frequency is chosen so that the quartz is not that big, and being 2^15, you can halve the frequency 15 times so that you easily get 1Hz

Great video - I own an SBGE255 and videos like this help me appreciate it even more.

Very well explained sir . I think vintage omegas f300s are the best alternatives to the spring drive watches. They cost little and run at 300hz hence smooth sweeping seconds hand at a cheap price

Another great series! I hope its just the beggining

[dandyroth]

Does the IC send power to the coils to slow down the permanent magnet, or does the IC (phase comparator?) open a mosfet to draw more current to brake the motor? Maybe dump it through an internal / external resistor? Would love to know the nitty gritty details

[michealjoseph]

Learned a new thing today...thank you guys

[donaldneo]

Will the integrated circuit corrode or degrade with time? Will it last as long as a regular mechanical watch?

[grandiora]

I wonder what will happen if in a couple of decades time, the internal circutry fails in this watch, would anyone be able to fix it. Or will it need to be completely replaced and then be dependant on part availability, chip shortage etc.

Stop hyping up Grand Seiko

I'm saving up for one and I don't need people jumping onto the hype train and then driving the prices up sky high

[videoaddict]

I love Seiko but this just seems like a Quartz with extra steps, I don’t know why I don’t like the idea of a computer in my watch unless the display is digital like in my Casioak

[marius]

Hello!!
Spring drive is like eco drive?
Eco drive from Citizen

[walterking]

Call Rachael Little girl, I love it I would like to know your opinion what do you think Ground Woker can drive it worked

[OLOLAK_]

With the price tag that cost heaps n heaps, I rather drink all that alcohol in the background bottoms up luka 🍻 🤭
