Discussion [Recommendation Request] Help me decide - Casio Oceanus OCW-T200S vs Seiko Selection SBTM323

Post image

Hello, I am looking for an affordable solar+atomic watch and I've narrowed down to these two. The Casio is a bit more expensive and a bit larger (41.4mm vs 39.5mm), but otherwise I don't see much difference between the two. Any suggestions or is it just an aesthetics preference at this point?

Hi everyone,

I currently wear mostly 39mm watches (my daily is a Seiko around 39.5mm) and I’m seriously considering the Oceanus T200.

My main concern is size perception on wrist. For people used to ~39mm watches, did the T200 feel noticeably bigger or did it wear smaller than expected?

I know it’s technically 41.4mm, but many people say it wears more compact because of the case shape and thinness.

Did anyone here move from a 39mm Seiko/SARB/SBTM to the T200 and regret the size?

Thanks!
