To be fair it's a nice example of a VFA.
It's worth more like 3-4k though, not 25.

So the five 6186 8000's currently listed on YJ ... only add up to US$21000 ... and all five are in better condition
oh, and as I like a giggle when people are honest ... apparantly this describes the bracelet >> Band:Nice 100% original,stainless steel
HUH, since when was Maruman a Seiko company ... yes, you can argue the context of original (it is after all an original maruman bracelet) ... but no matter how you cut it ... it ain't OEM
Actually for 25K you could fly to JPN, have a nice (maybe short!) holiday, pick up a 6186, and arrive home with a smile on your face ... just a thought!

Long story short, the 6186 is a turbocharged version of the 6106. So the mystique aside, they're just a highly tweaked version of that movement. They are more like a highly tuned Japanese car rather than a hotrod. So refinements for improvements over just dumping more bits on it to make it go better. A Honda engine over a Chevy. It's regulated, balanced and thermally compensated, along with other tweaks. How do they do this? Some dude in Japan manually balances the balance wheel. They often use a better grade or hand picked hair spring and mainspring. The entire train is jewelled. The pallet fork will be hand picked and balanced, the pallet stones probably hand picked as well. Often these springs are aged or treated in some way to get to ideal performance before assembling the watch. I don't have any specific details about this but have read before these sorts of things do exist and there is a documented secret art to it. They also regulate under multiple temperature conditions and in 6 positions and at the time would have used synthetic lubricants rather than mineral oil lubricants. A standard 6106 is stamped out with practically zero tweaking or balance. They perform reasonably well because they tweaked the machine process to get them to perform within a certain range, all the time. But it is a very similar beast. ETA movements are the same. That said, the Nivarox springs are very good. SEIKO have a similar higher grade spring (SPRON) they use for their ETA grade equivalents. Hope that sheds a little bit of light on why these are different. To be fair it's a nice example of a VFA. It's worth more like 3-4k though, not 25. My Knowledge is sadly lacking. I wouldn't have given this a second look but then the high end stuff was out of my range. |

What's a Remex?  That watch has been relisted over and over and over and over and the one time it was listed as an auction it sold for or was ended 5 minuted before bidding ended it sold for under $3K if I recall. |

Yes there is light at the end of the tunnel and thanks for your time and trouble. It draws from other areas as well. As per the JDM tuners the various automakers in Japan did not send abroad be it restrictions for safety or emissions. These vehicles now past the age requirements for import are now coming to N. America. A lot of them and their performance capabilities unknown to the masses.
As to metal treatment, one thing that comes to mind is an old process where the bed for table saws were cast then aged for a time, allowing for warping in the curing process before planing for flat. Time is money and this is lost in the manufacturing process.
Ajdt. to 6 + temp is not up to mass production. I guess -15 to +25 isn't bad for production line work.
