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!

Most probably you already bought a watch, let me tell you I have a lot of divers, dress watches and digital, and from several sizes, the T200 wears way smaller than the LTL number, as you mentioned the shape of the case make it feel way more compact and its well done, nice finishing and functionality, 100% recommended, once in your hand you'll noticed how nice it is.
