Thanks for the note. I think a custom date ring made from scratch is the order of the day. Does anybody know what font Breitling actually use? I know they have the single digits oriented parallel to the tangent and the double digits perpendicular... If you can get hold of OEM datewheels from Breitling for the navitimer these probably could be modified and used. Can these be obtained?

Hi guys, anybody got/seen a good copy of the ladies carrera wv2413 thanks

Thanks Toadtorrent. Glad to see a great deal of enthusiasm for this idea. I think we're reaching critical mass

Certainly can wait. PM me Cousins have responded quickly to a request but don't have an image of their 3LZF1 without the dial, which I would very much like to see.

Great news Francisco. It seems that you're the man for this sort of thing around here. Nice work. On a side note I noticed that your regulator mod appears to have vanished into thin air. Do you know what the deal is with this and could you repost it?

FYI

Good deal Bibbs, I like your idea about recessing the first plate. This is the solution for the engine I pictured initially I'm sure. For the second engine, pictured by Rolexman (original from yodap) the job of modifying the plates is not needed. However, some support for the inner edge of the new date ring will likely be needed in the areas of the date window and the gears to prevent any inner edge dipping which may be visible in the date window and might interfere with the gears. Last night I spotted your previous posts on the subject. Glad I'm not on my own with my thinking. Thanks trailboss, do tell; that would be great

Good job fella. Sweet. Would love to see this though with the dial removed.

Thanks for noting my point about optimism. Given the photos provided by yodap of one of these mechanisms I'd say that it is really easy to do. I just need to get my hands on one of these so I can get this done. http://www.auctiva.com/hostedimages/showim...,0&format=0 I hope you take all this back when I manage it

looks like it's actually from yodap

Hi Watchdog. To be honest the more I probe it looks like this mod is fairly easy; based on what I've seen here and my engineering experience. I do some experience with watches. Lets try and be optimistic. THE main flaw with these watches is the deep recess of the date ring. Please try and be constructive. Lol re posts. I figure that the best way to get appropriate responses is to ask questions in the appropriate forums. I may be new here but I'm not new to forums and I used to be one of those guys who lurks in one specialised area and wouldn't notice if somebody asked a question that I could answer if they posted it elsewhere. You should consider the internet fortunate that I'm keeping it to just this forum lol thanks p.s. looks like the image belongs to andreww

Nice find Rolexman! Gee whiz. That thing is just about perfect for modifying. No need for cutting down anything just putting a thin lip on the existing date ring and bonding a new one above the gears. Does anybody have any clues where this image is from?

Am considering modifying this mechanism so it has a far better date recess: http://www.rwg.cc/members/Navitimer-date-f...677#entry657677 I need a working or broken engine to make a prototype on. Any body have a broken one that they could donate/sell to me? Or, anybody have an idea where these can be purchased? Or, at the very least which is the cheapest rep with this movement so I can go about getting that. Thanks

Glad to see that people can envisage what I'm talking about and don't think it is too ludicrous an idea. I wouldn't say that the difficulty in modification is such that it probably isn't worth doing (since I'd give my right nut to have any of the 3,6,9 replicas without the ridiculous recess) p.s. can't see your image What I need to know is where can I get hold of an engine to try this out. Can the Asian engines be purchased somewhere? Does anybody have a broken one of these that I could have/buy to make a prototype with? Thanks

Cheers for your comments Bibbs. You've pretty much the idea. Except you would need to do it to the second plate too; since there has to be a continuous gap around the engine for the date ring. cheers, lol Erm, No. I just haz a clue that's all I'd bet that this can be pulled off.

Thanks for the note but I believe that it is optimism that advances things such as technology.

Hi guys, I've been pondering the 3,6,9 a7750 and the problem it causes with the depth of the date ring and I think I have an idea how it can be modified http://www.rwg.cc/members/Navitimer-date-f...637#entry657637 any thoughts would be really useful

Thanks for your quick responses. I have found this, since I noticed that other models in the 3,6,9 configuration apparently use a similar (same?), modification. Thanks to Francisco we have these of the Omega seamaster: These show the engine with the dial on, the dial off, the first plate off, and the second plate off. After seeing these I'm quite optimistic that this issue can be resolved so the mechanism can be modified. These plates have cogs that overlap the date ring partially, but in no place, on any of the plate is the date ring completely overlapped. This means that a little reengineering may solve the issue. Here are the steps of modification I can imagine taking place 1) tap second plate into bridge on engine so it attaches above the mechanism via the bridge rather than the edge. 2) tap the first plate into appropriate parts of the second plate so again it does not need to attach at the edges of engine 3) grind the edges of each of these plates as far as is suitable to keep fit of cogs (only exposure of a circular area covering the outer few milimeters of the date ring is needed 4) add a appropriate spacer and new plastic date ring which thus bridges the two plates thoughts.... thanks

Hi Guys, I'd like to open by saying what a great forum this is. Lots of info. I've been reading around about the Navitimer replicas and in the reviews the prevalent issue appears to be the drop out of the date number. This is a big deal to some I'm sure. I was wondering if anybody has taken a good look at this to see if it can be modified to be raised to a more appropriate position? Are there any pictures of the modified 7750 with the dial removed? This would help clarify what the problem is and how a little modification might be possible. thanks
