Hello Experts,
I have been a keen reader of the Omega forum,but this is my first post,and although I own an Omega AT already, I am a newbie in the world of automatics - so I seek license for Naive questions

My Dilemma: Whether to buy Seamaster Chrono Diver Chronograph (Calibre 1164) or Seamaster regular Chronometer (Calibre 2500)

why am I confused ?

300m Chronograph (Calibre 1164) : 213.30.42.40.01.001
- Love the complication with 3 dial chronograph, but i have a 6.25 inches wrist, and it feels a bit too thick, although may be manageable and needs getting used to - not very sure
- I see good reviews about Calibre 1164 stating its sturdy etc. but is modified Valjoux 7750 a good one as a keeper ? I dont plan to sell it, so durability is important
- Discountinued model, so bit of a collectible
- may be its my mind,but the steel on steel felt more solid than the ceramic bezel one described below

300m Chronometer (Calibre 2500) : 212.30.41 20.01.003
- Smaller size in terms of thickness, fits my wrist better i think, but is understated
- Has a ceramic bezel : my jeweller is saying it might break, would be costly to replace
- No chronograph, plain and rather classy look than sporty
- Movement is Co-Axial, which on paper seems more advanced than 1164, but is it a real showstopper ?
- Its an in-production model

The prices are almost same. This is going to be a very special watch for me as it will be an anniversary gift from my wife, so i dont want to go wrong

Urgent help appreciated


Many thanks

 

I have both watches and find the chronograph too heavy and chunky for me. I much prefer the look and feel of the 300M Professional Co-axial. As far was the movements are concerned, I'm not versed enough to say which is better, but I have had no issues with either one. I doubt you will regret either watch. Good luck.

 

The 1164 is based on the Valjoux 7750 - a tried & true workhorse capable of very accurate timekeeping.

The 2500 is an ETA 2892-A2 that's had the co-axial escapment modified and stuffed into it - and not with great results. However, the 8500 has been engineered from inception to work with the proper version of the co-axial escapement and seems to have cured the sudden stopping issue of the 2500.

If I were you and was looking for an SMP, I'd search for a pre-2500 model that houses the caliber 1120 - which is the ETA 2892-A2 before the attempt to stuff the co-axial escapement into it. Otherwise the 1164 would be my choice.

 

+1, unless you really dig chronograph function (which probably not because your other option is plain Cal 2500), I suggest you check Caliber 1120 or its variation (with GMT for example). There are three models that I suggest: the black dial 2254.50, the Great White and the Electric blue dial (in SS or Titanium). All three of them mimic the design of the famous big triangle SM 300.
