    Hi Omega experts,
    can someone please inform us about the weight of titanium vs. steel Planet Oceans 600.
    Models 215.90.44.21.99.001 and 215.30.44.21.01.00.
    Thanks,
    Berni

    Why?

    Because Titan has half the density of steel. So it is interesting to know how much the Titan version is more lightweight. It will maybe not 50 %, cause the mechanic inside is the same.

    Hi Berni, experts we aren't but enthusiasts we certainly are, I can't help with those specific models but i know that titanium is just over half the density of stainless steel, i think about 4g per cubic centimetre, and 316L stainless is about 7 or 8g, usually Omega reply back with data sheets or specific info on models if you can't find what you're after on their website, they're quite helpful especially when given specifics

    Thank you for your answer. Strangely, Omega does not state the weight of the watches on the technical data sheets.

    I did not measure it, but I have tried 43.5 Titanium PO while I had 42 steel 8500 PO. There was a difference.
    42 SS PO with almost full lenght bracelet was something just under 200g, 43 Ti PO was significantly lighter, under 150g for sure. It is not half of the weight of steel, but I guess it is 1/3 less.
    If you are looking for a weight relief - Ti PO is good direction.

    It can go on the strange list then, strange they don't publish it so the weight is easy to look up,
    I would have thought it would be treated as quite an important figure, my train of thought being that because they (Omega) hold the First Watch On The Moon title, and weight of equipment during space travel being quite a big deal, because of the cost to get it out of Earth's orbit, the weight of each astronaut's watch collectively would surely have been factored into calculations, but this is actual rocket science and a rocket scientist i am not, plenty of folk on the forum will confirm that,
    But as a separate question, why weren't the astronaut's watches made of Titanium in the first place, just to save weight,
    now i know for definite i have too much time on my hands

    I don’t know specific numbers, but I did try on a titanium PO GMT model last year and compared to the steel. The titanium was noticeably lighter and I could have lived with it (even with the ridiculous thickness) but couldn’t talk the AD down too much from the much higher price. The steel was just too heavy for me to even consider, unless I wore it on a strap.

    The reason I said why...

    it doesn’t really matter much in real life. Unless a heavy watch really bugs you.

    You don´t make the decission more easy, cause the black Dial of the steel version looks better for me. :cool:

    I own a 45.5 3313 on bracelet... sure it’s heavy but you quickly get used to it. Titanium is also non ferrous which has some applications for people.

    personally get the color combo you like best. Is my advice.

    The question was answered by Omage:
    215.90.44.21.99.001 - Seamaster Planet Ocean 600M - Titan: 140,14 Gramm
    215.30.44.21.01.001 - Seamaster Planet Ocean 600M - Stahl: 214,00 Gramm
    So a Titanium is 34% more lightweight than a Steel SPO
