Seamaster 300m midsize thought

Hi all,
I’ve been in love with the blue seamaster 300m at first sight, one day or another I’ll get one.
As 41mm may be too big to me (I’ve got a Blackbay ETA which a love, but it is big!), I’m also looking for midsize version.

here is the point:
Most of us seems to love « small » diameter, but the midsize Seamaster 300 seems to be less appreciated than the 41mm.

is there a main reason? Is the movement from the midsize less interesting than the 41mm version?
Anyone who has feedbacks about owning the midsize?

maybe I’m just missing something, let share it 😀
I have the model in the pic you posted (2551.80) and love it. Wrist size is 6.5 in. Here's a wrist shot:

Well all I can say is that if the midsize is good enough for Prince William, then it's all good..... 😉

It works really well on your wrist!

Thank you! I'm just not into the "big watch" thing that's been going on the last decade or so...

I’m sure it would be really nice on a vintage leather strap.

It would be great if someone has the opportunity to take 2 wrist shots, one with the midsize and another one with the full size.
It would be interesting in order to compare...

by the way, my wrist measure 18cm, but I guess it is also about the shape, flat or rounded etc.. (just talking about wrist uh )
A bit late to the party. I’ve got both, wrist size 6’3. I prefer the midsize. First pic is the comparison of the 2, the other pics are the midsize.

Yeah, I think the midsize looks a lot better on your wrist. The full size doesn't look awful, but the mid is simply a better fit, IMO.

My midsize doesn’t suit my wrist while on the bracelet, but I’ve got bigger wrists.

All I’ve done is put it on a NATO strap and it’s made the midsize wear a lot better for me. The NATO strap has propped the watch up on my wrist with the fabric running under the watch.



It’s the only Quartz I have in the collection. It’s fantastic for just picking up and not having to wind etc and incredibly accurate, so a quartz still has its place for an easy grab watch.

I would recommended trying on both to get a feel for which one your like, that’s probably going to trump everything. If it doesn’t, consider your wrist size. As someone mentioned before, anything wrist size below 6.5 will look bettter with the midsize version. It looks more proportionate and cohesive with your wrist. That been said, I love my midsize smp, but I have 5.5in wrists .

One thing to note is that the 41mm case of the older Seamaster Pro wears substantially smaller than some comparable 41-42mm watches because the lug-to-lug distance is smaller. On the Seamaster Pro it is 45 mm and the lugs have a significant curve to them. My Seamaster 300MC is also a 41mm case, but the lug-to-lug distance is 49mm and the lugs are flatter. It wears substantially larger than the Seamaster Pro.

You really should try the regular size on before ruling it out, if you can. When I bought my first Omega Seamaster back in 2005, I went in expecting to buy the midsize, but found the 41mm case fit nicely, and I liked the bigger dial. I walked out with one of those instead.

Hi,
I am interested in buying a pre owned mid size version. Most of them are advertised as 36mm. Others as 36.25mm. Are there 36mm versions out here? Perhaps older models? I know it is only 0.25 difference, but since they are already pretty small, I would like to know for sure. I have a black bezel version of the year 2000 in mind..
Anyone knows? Thanks

I think the mid-size ones were all officially 36.25mm

To be honest, I don’t think .25mm would make a big difference.

I think your right, when you put calipers to it it is around 36.25 or so a little larger than 36. I recently got one and am very pleased with it. I was concerned about legibility as I’ve read here the bezel makes up a lot of that 36.25 making the dial very small but TBH it seems fine I have no problem reading the dial. I think the size is fine and if you wear a lot of vintage, your used to this size. It’s low key as well which I like although In the future I wouldn’t rule out getting one with another 5mm making it the “full size” but I’ll see what life has in store, one never knows for sure.

I guess you’re right. 0.25 does not make a huge difference. I found a pre owned seamaster from 2000. Does anyone happen to know if these were done with super luminova at the time? I like good lule on my watch.

It has a reference number 022525000. Not sure if it is manufactured in 2000. It was bought new in 2000.
Would this be super luminova? The price is very tempting. 2400€ for an automatic in mint condition..

You can tell from looking at them, the earlier tritium models have lume that is much more beige in colour and usually the hands and dial have faded to different colours. Omega switched from tritium to SL at the end of 1997 so if the watch is truly from 2000 (and didn’t sit on the shelf for 3 years before selling) it will be using SL.

it sounds pretty expensive to me btw.

Thanks for the tip! How can find out when it was manufactured? Where would you look for a good second hand btw? I found this one on Chrono24

My 41mm Seamaster 300m is from '99 - 6020 serial number and has the tritium dial/hands/bezel insert - if you search around on chrono24/eBay there are a few from '99 with the tritium instead of SL - I guess it's all speculation as to how these tritium dials ended up on watches made after '97...I've never been able to find a definitive answer? I even saw a full size seamaster quartz with 2006 papers and tritium dial recently sold on eBay - very odd indeed..😵‍💫

Edit - having looked at the watch with 2006 papers again, seems it's a 595 serial so guess it took a long time to sell!

I can not seem to find any way of finding out when this watch was manufactured. When i cross check the serial numer online, it says it was made in 2006. He definitely bought it in 2000 in a an official omega dealer in Holland. He can t tell me when it was manufactured..
