### ⭐⭐⭐ Received Different color

### ⭐⭐⭐⭐⭐ excellent.

Best watch ive ever owned , better than my tag formula 1

### ⭐⭐⭐⭐ Really Like Ratio - REAL dive watches!
*by O***Y on 22 March 2026*

Ratio's are excellent watches and a great value for the price. It's an automatic watch (i.e. all mechanical, no battery) and it keeps excellent time. The lume is as good as my Seiko's and Citizens. One thing to note, however...the pictures of this watch shows a Ver. 2 of this watch, and the model number is for a Ver. 2. However, I don't believe this is what I received. I believe I got a Ver. 1. It's the same size, same movement, but the main difference is the Ver. 1 has an oyster red dial, and the Ver. 2 has a flat maroon dial (pictured). I would have much preferred the flat colored dial over the oyster version (very much preferred). I took one star off an otherwise 5 star watch for this. I don't like misrepresentation. This was a hard review for me to write because I love these Ratio watches, but the dial is represented in all the pictures as flat (not shiny), and the dial I received was oyster (shiny). It's a real dive watch though, so I'm keeping it. Oh, and the strap is a nice flexible silicone, but I switched it out to a nicer velcro strap with reflective badges on it.
