Absolutely beautiful!
Couldn't be happier with this watch! The dial is outstanding! I love the color contrast of the blue's it almost makes the dial look black! The Miyota 9015 gilt is stunning! Momentum hit a home run with this one! Hey, design department, A blue bezel with black dial on a titanium housing would be absolutely killer! Hint, hint... 😉

Aquamatic 4
It was good. The watch looks wonderful. There is a pin that holds the bracelet closed… After opening the bracelet about three times… the pin fell out of the bracelet!! I have crazy glued it back in, but was less than happy with that! I’m not sure it will stay in!

Excellent watch
Beautiful watch that is well made and works perfectly. Comfortable to wear and looks great.

Nice but not perfect
This is my only watch bought to replace an old Seiko I’d had for years. It’s worn day in day out (at least 2, maybe 3 years) and until now and has been consistently reliable. Overall very happy with it but recently I noticed the little luminous pip at 12 o’clock had disappeared! Not a big deal but at $850 I’d hoped it would outlast me…….not so sure now.

Watch came upon taking it out of the box. I noticed the magnifier for the date was a little crooked, so that’s a crystal was not put on correctly so that the magnifier was slightly higher above the window. I sent it back. The watch has been returned.
Thanks for your question! They are on the exterior of the crystal.
Thanks for your question. Unfortunately, there is no left-hand version. However, this one does have the crown at 4, which makes it quite comfortable and reduces "wrist-bite".
Currently, the Aquamatic IV is the only one in our line-up, but stay tuned for more on the way ;)
