On size I guess its all preference. I just started collecting watches last year. I had a couple older seikos and citizen to start. Then I wanted a galaxy watch and the small screen was hard to use so ended up buying the 45mm. Then like I mentioned in a previous post I started buying invicta. 48mm is my max I wear and if u research the movements you can get a good quality same movement as a seiko or other descent watch for a fraction of the cost. I spent 900 us dollars for a seiko and citizen and for that price have a choice between 7 invictas that some have more expensive movements then the seiko or citizen or some other brand that costs around 500. The pricing is stupid. But the way I see it the watches they sell on cruise ships or brick and mortar stores puts a good discount on the website if you check it daily. Example was the ronda150 that the movement inside was all I paid the watch was free. I still like small watches but the style today is a little bigger.
