Does anyone know whether the dial feet changed between these 2 movements? I found a Breitling dial for sale, that looks exactly like what I need except it is being advertised as a 7733 while my watch is a 7730. Thanks
7730 was basically a Venus 188
7733 was completely redesigned but same fonctions as 7730
I think the position of subdials are the same but I'm not 100% certain ...

One can see dials as these at Ebay marked fitting 7730 or 7733 but as you say seldom together.
Probably not to get a too many franken watches beeing built. I have non of these needing service right now so I decided to make an experiment.
Take a random picture from one who sells a dial to a 7730 dial and one who sells a 7733 and superimpose them over eatch other.
A fun excersize on a sunday. The result except from a slight skewness in the pictures shows the dial feet are at the same place.

I can use any info! Thanks
The original Venus 188 and the early 7730 had a flat pillar plate.
The later 7730 and the 7733 had a beveled pillar plate.
What you could do is to remove the dial from your 7730 and check if :
- your 7730 has a beveled pillar plate
- the holes for dial feet are about 12:45 and 8:15
If YES then a 7733 dial may work.
If your 7630 is an early one and has a flat pillar plate, then probably not.

I appreciate that the original post is a little old now, however thought I'd share some info to assist this and others that may have similar questions.  So I have a couple of Cal 7733s and a recent purchase of a 7730. As called out in previous responses, there are two variants of the 7730, with either a flat or beveled pillar plate - mine is the beveled, the later version.  

Being the newer beveled version, I was expecting a 7733 dial to fit nicely, however it does not.  Whilst the dial feet are in the same positions and the sub dial pillars line up nicely, the bottom dial foot (midway between 7 and 8 clock) is marginally closer to the centre of the movement that on the 7733.  

So in summary a 7733 dial does not fit my 7730 movement.

I hope it helps..

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
