Best in its class under US$550
Casio make a high end line called Oceanus. OCW-T4000CL is a high tech modern model with beautiful finishes. It has solar power, that means you never need to change the battery. It has Titanium case which means it is light and tough. It has Anti-reflective coating Sapphire glass which means the glass is very clear and almost no reflection. It has Zaratsu polishing which means the case is smooth and beautiful shine. It has world time and you can read both local and another city time at the same time. It has bluetooth connect, that means you can connect it to your phone and update the exact time 4 times per day and accurate to the very second. It has Multiband6 which means it can receive standard radio waves from 6 stations around the world and be able to automatic time correction. It has excellent value and beautiful and functional all at the same time.
I collect Casio watches, including Oceanus, Edifice, Lineage, Waveceptor.
I like the Oceanus line but not a fan of the bluetooth equipped models..
Multiband reception is fine for time correction every (just about) day or so.
4 times a day correction is overkill.
I have a few radio controlled watchesand don't have a problem getting reception from Colorado here on the east coast.
I like this model
Casio are awesome.
Personally I'd get one without leather because that industry is really nasty.
This one has everything except Bluetooth and a coffee dispenser for 160 bucks.
Not Diahatsu polished but very good finishing.
A shame the Oecanus line seems to be JDM only, the T200 is a really interesting model.
Big fan of Oceanus got my first one a few weeks ago and hope to get more in the future
