I am wondering about the applied indexes on non A/C dial.
Did you guys have to replace a cannon pinion (for higher) to accommodate the non A/C dial?

No I did not

This is something you really need to be careful of. It's not just the cannon pinion, but the hour wheel and the seconds hand as well. All three posts may need to be moved up higher, and you also need to be careful that you have clearance under the crystal.

The need for increased lengths on these parts will in part be determined by the model of watch you start with, and what the posts on those watches are at in terms of height.

So the watch the non A/C dial comes from is the 22305000, and the movement is an H3 hand height:

7221120300273 | SECOND WHEEL H3 5.11

Note the length of the seconds wheel is 5.11 mm.

The most common starting watch for this mod is a 22545000, which is an H1 hand height:

7221120300271 | SECOND WHEEL H1 4.61

So you are already using a seconds wheel that is 1/2 a mm shorter than it really should be. This doesn't sound like a lot, but in the context of hand fitting it certainly is. It can be made to work though without a huge amount of difficulty.

But if you were to start with say a 25318000, that is the shortest movement height, so H0:

7221120300270 | SECOND WHEEL H0 4.36

That is a full 3/4 of a mm shorter than the height this dial was designed to work with, so in order to make this work without using longer parts is going to require some very unprofessional bending of hands...and you still may have problems...

People assume that all 1120 movements are the same, and clearly they are not, so for those who don't understand this there are hidden compatibility issues that can bite you in the arse when trying to do these mods.

Cheers, Al

I never understood the fascination with the "non-AC" dial. I prefer printed plots and logo every day of the week on a tool watch, to make it less blingy (think of matte-dialed submariner 16800 vs gloss dial with gold surrounds). I also hate how like on the PO's the shiny Omega logo disappears on certain angles vs the printed logos of the original 2254.

It looks great in pics but I am curious for anyone who did it: is it noticeable day to day? Does it look good enough to justify the cost ?

It is noticeable. It looks awesome. It is a common mod for these reasons.

The dial looks awesome in any SMP configuration, including titanium! Here another picture of the dial on a 2231 with Speedy style 1610/930 band 😀

Ive had this watch for a little over a year now. Recently had @Archer service it. Such a great watch and the dial is stunning! The white gold bezel is unique.

I've been wanting to go with a rubber strap for the summer on this. Struggling with black as it doesn't feel quite right. A grey would be nice with the white gold (as it has a grey hue to it). Grey Nato wouldn't suck either I bet.

Non AC dial on 150th anniversary SMP 😀

Was that the grey dial LE version? If so it seems a shame to swap out the dial!

I love my Non AC, it’s much more special than the 2254 to my eye. I feel the same about the titanium 2231 also, the over big numbers on the 2254 anodised bezel never sat well with me, they are rather more subtle in the gold and titanium models. My 2230 Non AC:

Yes, the grey dial and the 18K WG bezel
with painted numbers of the 2232.30.00 :



had been replaced by the 2230 dial and WG bezel insert, plus a black date wheel and PO second sweep hand:



The 150th grey dial is unique among the SMP’s but prefer the black dial of the Non AC model with its raised logo and metal framed minute lume markers (happen to have another one as previously acquired another one loose):




Am anyway keeping the original dial and other parts from the 2232 so can have everything swap back to factory later if the desire to do so comes; am mod friendly as you can see and have it now just the way I want it 😀

Just did a search on the 2232 and interestingly one of the top hits was you selling one! I am curious about the bezel originally on the LE, is that the same steel insert used on the 2255? It looks to have the same blue/grey paint infill. The titanium inserts are rather more matt than the one you see on the 2232 in pictures. Some sources have the 2232 bezel as 18K gold, but it looks much more like the steel one from the 2255 than the WG one you see on the AC, Non AC etc.

The Omega 2255 has a steel bezel insert while the bezel insert of the 150th is white gold, here by itself:



It weighs 4 grams:




I have owned three different 150th SMP's, the current one twice (buyer sold it back to me as decided wanted something else), that's why you will find a couple of for sale threads from me on that specific model.

Interesting! It seems perverse that Omega would create 2 inserts that look identical, one in steel and one in White Gold but I guess it shouldn't really surprise me. Looks like the online descriptions are correct. Doent it make you nervous pulling the inserts out the shells, particularly the softer metal ones in gold or Ally? What do you use?

The regular steel insert of the 2231 and 2255 and the WG insert of the 2232 does look similar. Given the replacement cost of the WG insert of the 2232 is much higher than the steel version it is prone to be steal / swapped from 2232's. In fact, am almost certain that the insert on the first 2232.30 150th SMP I had was steel and not WG based on its look (never removed it to weight it). It does not makes me nervous to remove the bezel assembly and the WG bezel insert from it as have the right tools for the job.

All good but one minor correction, AFAIK the 2231 uses a titanium insert, so in summary:

2230.50 (Non AC, Black dial with applied indices and AML, Steel case) - Textured White Gold bezel insert with numbers cast in relief
2231.50 (Black dial, Titanium case) - Matt titanium insert with black infill
2232.30 (150th LE, grey dial, Titanium case) - Polished White Gold insert with blue/grey infill
2254.50 (Black dial, steel case) - Black Anodised Aluminium insert
2255.80 (Electric Blue dial, steel case) - Polished Stainless Steel insert with Blue/Grey infill
2531.80 (Bond Watch, dark blue dial, steel case) - Blue Anodised Aluminium insert
2533.50 (Americas Cup LE, Black printed dial with AC text, steel case) - Textured White Gold bezel insert with numbers cast in relief

Why do it the easy way when you can do it like this lol.

2531.80 (Bond Watch) - Blue Anodised Aluminium

Am not sure if the 2231 Ti SMP has a titanium insert or if it's just a steel insert; don't recall it being lighter than a polished ss one (did not weighted it). As for removing the bezel inserts, have the vertical press shown below with multiple plastic and metal dies, which makes the job pretty easy:

I am pretty sure the titanium watches use a titanium insert, excluding the 2232 of course. I have access to an XRF metal testing gun at work so next time I wear my 2231, I will XRF check the insert. The finish looks very much like circular brushed titanium vs any other metal to my eye.
