ETA 6497-1 conversion to 6497-2

[FxrAndy]

With all the discussion about 6497-2s going on a while ago i decided to look at the options available

A, buy a 6497-2 well if you can find one they go for a premium as we have found out at about €345

B, Use a seagull well yes i agree that they are great movements but some people just want swiss

c, Convert a 6497-1 to a 6497-2 with all swiss parts

Option C is what i chose to do, change every part from the spring barrel to the escarpment for 6497-2 parts

201 B Minutenrad ohne Minutenrohr 920002016499

210 B Kleinbodenrad 920002106496

180 B Federhaus mit Federkern 920001806498

224 B Sekundenrad mit langem Zapfen unten 920002246496

705 B Ankerrad 920007056498

710 B Anker 920007106496

721 B Unruh mit Flachspirale 920007216496

Total over €150 not Including tax

Plus postage

On top of that you need to add the cost of a 6497-1, oh and there

(if you are going to change any of the wheels, including the escape wheel or spring barrel you need to change them all as the 6497-2 has finer teeth)

But when assembling i accidently refitted the low beat balance to the movement with all the 6497-2 parts and it ran great but at 18000bph

So what if you just fit the hibeat balence to a 6497-1??????

I dont know yet because i have not done it

Photos to follow later to back this all up

The running movement

6487-2 chronometer balance fitted

All the old parts

packaging of some of the new ones

Running sweetly with rough regualtion and no oil yet

I've always wondered this: what the heck is the difference between a 1 and a 2? Is it just high beat and low beat?

[FxrAndy]

In pricipal yes that is the difference, i think all the 2s are chronometer certified, by panerai any way.

interesting read

[FxrAndy]

Well after all the hype about 6497/2 this should have been a hot topic, never mind

[Rolexman]

Well I thought there was no difference between 1 and 2 when it comes to beat count. The 1 is non-decorated and the 2 most of the time has nice CDG and Perlage.

[FxrAndy]

Nope the 2 is hibeat and the 1 is slow, you can get some realy nicley decorated 1s

And to continue with I would like to confirm that you cant just fit the hibeat balance (as suspected) it runs great but you will have a day only 16hrs long
