Turning a Valjoux 72 into Rolex 727

[powerloader]

Just lookimg for an alternative to Phong who is way to expensive.

If you source the parts (assuming they actually fit your V72 (the parts I got from Phong did not fit mine)), Ziggy can probably do it for you.

Merry Christmas to all!

Back on subject, would any experts care to share with us what the specific differences Rolex made to the standard 72 movement to create the "727"

Thanks.

On the 727 Rolex changed the balance and upped the beat from 18,000 bph to 21,600 bph. This modification entails the replacement of 15 parts, screws and clamps. It makes the movement more precise than the older movements. This is from "Rolex Daytona, a legend is born".

All phong is going to do is replace bridges and make the 72 look more like a 727.

As far as I know Rolex based its 727 on an updated/improved V72 which is called V726 and already has a beat of 21,600 (I have one of these in my 6263) perhaps this is the reason Phong's parts don't always work. You can read more about V72/726/727s here.

I didn't replace any movement parts in my 6263 since I'm saving up for a gen dial, bezel etc. which is way more important to me than a correct movement bridge.

"All phong is going to do is replace bridges and make the 72 look more like a 727."

I remember reading somewhere a few years back that the better rolex signed replica bridges were genuine V72 bridges cut down and restamped/replated. This may be the models that fit with no problem. There were a few comments about the bridge being a little thinner than it started out but other than that they were Ok.

I just now looked at my Wakmann with V72 and the stamping on the bridge is shallow but it would still show as being ground down and restamped because the jewels would not be as deep in their seats and the bridge would be a little bit thinner.

I do not know when it was made (probably 1960's). It has '72' stamped under the balance bridge and Incabloc shock protection with rose plating on the plates and bridges like omega.

I know next to nothing about genuine and replica Daytonas and V72 in general...but I do have a V72.
