Seamaster 300m Diver v. Seamaster Master Co-Axial
Discussion
Like both of these. The former is £1,500 less and has the 2500 mechanism and the later has the 8400 mechanism (with display back).
Any thoughts on whether the later is worth the premium. I actually prefer the looks of the cheaper one but don't know if it's accuracy and reliability will be less than the newer mechanism.
I will admit to this being a new area for me guys. Grateful for your thoughts.

My ill-informed opinion:
I wouldn't get the former just because I prefer the older 2254.50 design.
I wouldn't get the latter just because I prefer the original upon which that is based. However, it is a co-axial movement so technically it is impressive and that is what you're paying for. I mean... George Daniels. https://monochrome-watches.com/omega-explains-the-...

I've had the former for three or four years now. It's been impeccably accurate and reliable so I'd not worry about that.
I have other watches but seem to wear that one the most, which must say something.
Likewise - I have the former and it's probably the watch I wear most. I have other watches but seem to wear that one the most, which must say something.

Well, both of them have co-axial movements. I have the cheaper one (and an original SM300) and wear them both frequently. The new one is accurate to a second a day and is bomb proof. The original with a caliber 565 in it is accurate to about 20 seconds a day. Maybe.I wouldn't get the former just because I prefer the older 2254.50 design.

I'm not a fan of the Seamaster 300 Master. The fake aged lume puts me off.
Both very good watches, and both Chronometer certified by COSC in Switzerland over a 15-day period, so in terms of accuracy both are meant to be guaranteed within -4/+6 seconds deviance daily.
Aesthetically, I prefer the Master Co-Axial, but that's a subjective, personal choice for you.
The big difference is the movements within. Both are based on the Co-Axial escapement invented by legendary Isle of Man watchmaker George Daniels, who sold the rights to Omega.
However, how much the geeky tech differences really matters depends upon the importance you place on such matters, as you're unlikely to really notice many of the small differences day-to-day, except of course the larger power reserve, and you should try them on, as the 8500 is thicker.
I'm no Omega expert by any means, but as I understand it:
- 2500 movement family was based on an ETA 2892, heavily modified by Omega to retro-fit the Daniels Co-Axial escapement. They went through models 2500A to 2500D - with the earlier examples having teething problems, but you can be very confident that the versions sold today are tested & true. A solid, proven & quality Chronometer Co-Axial caliber, but maybe not that special in absolute watch geek/tech terms.
- The 8500 was Omega creating a more in-house(ish) caliber, built especially around their Co-Axial escapement from inception (possibly now a three-layer arrangement vs. two, I'm not sure), so it's a more modern, cohesive movement, but also quite a bit thicker (making for chunkier watches). The big difference you'll notice is the power reserve - up to circa 60 hours, compared to circa 40 on the older 2500 series. It's also nicer finished, which is great to look at through the display back. It also has a raft of hardware improvements found in higher-end watches meant to improve accuracy (silicon hairspring, and now free sprung), durability (full-balance bridge more stably supporting the escapement on both sides; diamond-like carbon coatings on the mainspring arbors to last longer).
For my money, both will do the job very well day-to-day, and size/power reserves aside, you'll likely forget which you're wearing, but the 8500 is indisputably better, and if I had to - as a general rule - guess which would be most accurate, it would be the 8500.

UnclePat has smashed the advice! Cheers and thanks for your time, Sir!
Very tricky but I appreciate the difference between the movements. I'm reassured to a degree that the 2500 movement is at least reasonably accurate and reliable. To the novice, with the price difference, i thought the newer one would be night and day better. I think it's going to come down to the on wrist feel when I get to the shop - next week!
