    Hi all I was just wondering if anyone knows anything about the slight differences between the old MK40 models, I'm talking about the the colourful model with the blue AM/PM sub dial ref 3520.53.00, I have bought two over the years, the one on the right is dated 1997 with a serial number starting with 55 and the one on the left is dated 2005 with a serial number starting with 58

    20160501_175056.jpg

    As you can see I have changed the straps to preserve the originals.

    The differences are quite hard to tell at first glance but if you look close enough you'll notice this 20160501_175439.jpg

    The minute markers on the older model on the right are smoother and flush while the newer model has obvious indents at every minute, also if you compare the numbers and text it is much more finely printed on the newer model on the left, but one of the differences that isn't as clear on the picture is that the sapphire glass on the newer model isn't as clear as the old one, it has a slightly cloudy look about it.

    As you can see from the original advertisement for the watch, the ad closer resembles my older model ad1.jpg adresized2-small.jpg

    Is this a sign of a fake? or did omega make some slight adjustments to it's model before they finally stopped production? I hope there is someone out there that knows more about this watch, Thank you for reading and I look forward to hearing what you all have to say about the differences between these two watches, thanks again!

    During the production of this watch Omega switched from Tritium lume compound (on your older model) to Luminova compound (as on your newer model) and it appears that some other subtle changes were made to the dial at the same time.

    I've checked on the Omega Extranet and the current replacement dial has the markers that look like your more modern watch, so I don't believe this is a fake dial.

    Cheers, Al

    Thank very much for your reply That is great information much appreciated, I love the look of the old patina on this watch it gives it so much character, could I trouble you with one more question, I've been looking at this watch online it is for sale the picture isn't very clear 20160502_233628.png

    I believe the reference number is 3523.30, everything looks ok with the watch but I haven't seen this model with the red crescent for the date markers I've only seen the red crescent on the blue dial version, I thought the white dial only came with the black crescent for the day indicator, the picture isn't the best I will contact the seller and try and get better pictures, thanks again for your help.

    Best Regards

    The 35233000 should not have the red crescent on the date hand - should be dark grey.

    Thank you for your reply, yes that was my suspicion, I think I will stay away from this watch, what do you think happened with this one? Do you think the date hand has been replaced? I will send the seller a message asking if he knows anything about why it's red instead of dark grey.

    Thanks again again for your advice much appreciated.

    Another thing about this watch is the second hand is from the 35213000 model, correct me if I'm wrong but this watch looks like a mix between the 35233000 and the 35213000, the omega logo is recessed like on the 3523 but the second hand is like the 3521, the shop is located close by where I live I might pass by and have a word with the seller so see what he knows about the watch.

    I took some pictures of the watch in the shop, the seller says the watch is a Japanese market version, all the functions are working perfectly on the watch, scary do you think? 20160503_180315.jpg 20160503_180320(0).jpg

    Thanks again!

    Serial number appears to be 55174815 - if that is correct this watch has been modified from it's original state, as that serial number calls up a ref. 35218000 with the blue dial...

    Cheers, Al

    Thanks again for that info, I really appreciate your help, probably the dial has been changed by the previous owner, maybe he liked the red crescent with the white face, anyways thanks a million for your advice, have a great day!

    My MK40 has the defined minute markers and was made in 1998 (56- serial) according to an online database. So your older one was supplanted pretty early in the run.

    I'm currently looking closer at this watch for a possible future purchase. (40th birthday incomming, so MK40 seems the right choice ;))
    I love the speedmaster, but it's too big for my "vintage-sized" wrists. I don't realy love de reduced, especially the movement. This seems like a perfect sized watch, and good addition to my current collection. I love the looks and the movement with all its complications.
    Looking at some advertisements, I see 2 different references:
    (1) 35205300
    (2) 38205326

    Is reference nr 1 for the older one (and thus tritium lume)? Are there more references? > any idea's on this?
    I tend to like the tritium lume a bit more, because it ages more beautiful. > what's your opinion on this?

    I’m in the same boat with you. Also turning 40 and have been researching this quite a bit. It seems that the first reference you mention is the metal bracelet version and the latter one with the strap. So based on my research, these have nothing to do with the tritium etc. Serials 55xxx seem to be older, from the 1990s and 58xxx from the mid-2000s (towards the end of production). Somewhere around 56xxx they seem to have updated the dial a bit with clearer minute markers etc. Maybe this was where they switched from tritium to luminova?

    Yes, that appears to be the case. Like @Archer said above.
    My savings are reaching their goal...so probably incoming the next 2 months somewhere for me.

    My favorite would be one with tritium lume and metal bracelet, but it depends on what will be for sale the next couple of months (and at what price and location). Maybe one without bracelet is an option too (and then buy a separate bracelet) But the price our local AD asked for a replacement bracelet (1000 euro's) is not an option for me. Is this a normal price? Seems a bit too much to me.
