Seiko SKX007 movement replacement, 28800 BPH possible?

[Haribo]

I am looking to replace the movement on my old Seiko SKX007, mainly as a learning curve to get me used to opening and modding watches.

Before I purchase a new movement for the watch I would like to know what my options are.

What potential upgrades can be made to the watch if replacing the standard 7s26 movement?

I know that a 6R15 can be installed and will work well.

Can a higher BPH movement be installed? Are there any other movements that will fit without tricky modification?

What about some of seiko premier movements?

Why not buy a mm300? That'll do it.
Then fiddle with the skx007 all you like.

i understand hacking and handwinding,

I dont get 28,800 bhp, its not such a big deal for accuracy and fluidity, IWC and AP in house movements are actually 21,600 and Vulcain which is an amazing manufacture brand still uses 18,800 BHP movements.

I am a big fan and fond of Vulcain timepieces, particularly alarm timepieces and their magnificent movements. Their producing their own (In house) movements, as Seiko and Citizen also do, is another reason for me to respect this brand.

I didn't know Vulcain movements have 18800 bph! Thanks for the info, Alpinist.

To me, a smoothly-gliding second hand is pretty important, and it's a disappointment that some nice watches don't have one. If I wanted a stuttery second hand I'd buy a quartz. On a watch with a larger face, 28k is as low as I'll go, and I'll always take 36k given the choice.

I mean, all those "hi-beat" watches are selling to people for a reason, right? There's definitely a sizeable group of watch buyers for whom it's important enough to pay extra for.

Unfotunately, the vast majority of folks who buy expensive hi beat watches have no idea of what is inside then. They buy them for the prestige that a name and cost; it makes them feel impotent

Surely no one woud buy a watch to feel impotent... Just imagine all the dissapointed wives and girlfriends .

I doubt they do it to feel impotent =)

That aside, I'm skeptical of your claim. It's pretty easy to see the difference between 10 beats/sec and 5 or 6. People are buying Spring Drive and hi-beat watches when Seiko also makes parallel watches that are otherwise very similar, and I doubt many people are buying Seiko watches for the prestige and name.

I accept that many people who buy hi-beat watches are buying it primarily for something other than the beat rate. I personally will almost certainly buckle and get a Snowflake at some point, and even for me the dial is a bigger selling point than the gliding second hand. Plenty of hi-beat watches do have aesthetic charms beyond the beat rate, after all. But I doubt that a majority of those buyers are completely unaware of what the high beat rate is giving them.
