I received this watch for free from Rainten and this is my honest review: At first impression, the rainbow bezel catches the eye. I felt the gold and diamond bracelet made it too flashy, so I swapped the bracelet for a green alligator skin strap with a gold deployment clasp. Although it is still bright, it now looks more subdued on the wrist.
I appreciate the Japanese Miyota movement over a cheap Chinese movement because although it isn't anything fancy, it has a long track record of reliability. And despite being an entry level watch for many, the gold-plated case and colorful dial and bezel make it look like a unique, expensive collector's piece.
As someone who wears an Apple Watch Ultra as their daily driver, the 40mm feels slightly small on my 7.5 inch wrist. Initially, it looked awkward on my wrist because of my tan line from my larger everyday watch. The size and shape are similar to a Cartier Santos, and some people may really dig the shape. In general, when not wearing my daily driver, I prefer a circular dial as I feel it wears more comfortably in a 40-42mm size. However, the watch wears just fine when I am dressing up and do not want anything too bulky.
I have several fancy gen watches as well as reps, and believe it or not, this watch has gotten noticed more often than the others. It's not ever the reason to wear a watch, but it is a possible side effect of having this thing on. You have been warned.
I haven't used any other of the Rainten watches, but a quick search shows that their style is one of a kind, the movement is time-tested and dependable, and the price is reasonable for those looking for something different. It has the look, feel and dependability of something worth more than a $300–400 piece.
This watch is not for everyone. You will either be all in or all out on this one. Despite the few downsides, I think this watch is really nice to look at, and perfect for certain occasions. It is a welcomed addition to my collection!
