My MBW/MBKs are more than 2 years old & the factory may have changed the current design, but my stock dials glowed far too brightly for a 30 year-old tritium dial (which should have little or no glow at all). This is also 1 of the biggest design flaws on many aftermarket dials (the use of modern lume on what is supposed to be a vintage dial) & 1 of the main reasons I replaced (& separately relumed) my aftermarket dials
It might be worth detailing the movement options (V23 or V72) for DWs & similar case kits. I think you also mentioned that all of the 1165xx cases were too thick, which is only partially correct. Some of the early secs at 6 versions (like mine) came with nearly correctly sized middle-cases, which I referenced in the Build a Perfect Daytona thread awhile back. You might also include more details &/or links for your 16520 construction projects since these are pretty much the benchmark for frankenbuilders.
I am sorry to hear this. They are as iconic as it gets in the watchmaking world, but I think their demise is due more to their antiquated technology (relative to today's digital diagnostic tools) than anything else.
To the best of my knowledge, gen dials (& aftermarket dials made to gen specs) will only fit Valjoux 23/72 movements & their direct variants (like Rolex 727).
Because the sub dial spacing is slightly different, you cannot use a gen dial (or aftermarket dial made to fit a V23/V72) on a 7750.
I have never tried to fit a Lemania to a gen dial, but I am pretty certain it would not fit either.
The OP referenced By-Tor's reviews & included specific links, which tells me he put some effort into researching his quest before he posted. That, for me, merits a more in-depth response than the newbie who joins the frey with 'Who has (or where can I get) the best.......?'
Some good points there, Alli. The 2 models do have different crystals - T18 for the 6536 & T16 for the 6536/1, but I think the only difference lies in the height (I only have the T18 on hand, so I cannot do a direct comparison). Both cases should be 37mm x 13mm with 24-600 crowns (Brevet crown, if 'Brevet' is engraved between the lugs).
It all depends on the dial. Because they are usually sealed with a gloss coat, most modern (last 25 or so years) dials can be gently washed with water. But water can damage many older/matte dials.
Back to Ziggy's original post - it seems very unusual (to the point of incredulity) that a watch would (or could) leave Breitling's factory in that condition. I wonder if the watch had been 'serviced' someone else before it got to Ziggy? From the description, it sounds like the watch had previously been swish-&-dipped, which would make alot more sense.
By-Tor is usually pretty comprehensive in his reviews, even listing the collector/sources for all of the watches. If you like a watch that By-Tor reviewed, why not just buy 1 from the same collector?
The 6536/1 was powered by a chronometer-rated 1030, whereas the 6536's 1030 was non-chronometer-rated. The case & crown/tube was the same.
Some early 6536s were powered by an A260, which was never used in the 6536/1.
Patience, Grasshopper. Good things come to those who wait.
I certainly understand where you are coming from, but 1 of the beauties of frankens is that they can be upgraded, on a continual basis, as more & better parts come along. All you need is patience. You have come this far, so why bail now? And selling off most of a collection of wonderful frankens to fund a gen or 2 usually ends with a watch case filled with regrets.
Other than buying a new rep, I do not know of a source for a cheap replacement. However, you can buy a good aftermarket insert here. Also, because this insert is made to fit a gen bezel (or an aftermarket bezel made to gen specs), it may or may not fit a standard rep bezel.
Based on my experience converting a 1030 to 1036gmt (I have never worked on or converted a 157xGMT), in addition to the expense, you are likely to have trouble locating some of these parts.
