Eco-DIY is rated 4.7 out of 5 by 10.
Rated 5 out of 5 by from A smart versatile watch I bought this watch over the weekend. Normally I collect mechanical watches but having such a tough versatile watch that never needs a battery change so long as it is exposed to light appeals to me. This watch has two personalities. On the bracelet it is a great every day and casual watch but if you take a minute to swap it over to the silicone strap it is ready for a day at the beach or lake. Do yard work in it or help a buddy move without fear of scratching up the bracelet. Plus Citizen has a reputation for high quality pieces. It's basically 2 watches for the price of one.

Rated 3 out of 5 by from very nice watch but silicone wristband split apart i bought my watch on Royal Caribbean Cruise in 2017 and used it every day with the silicone wristband, i like it better and with normal use it stared to reap off, i don´t dive, i don´t snorkel, probably excercised with it a few times and showered with it too but not exposed to any situation that could cause that damage.. canb the people oc Citizen tell me where can i buy another silicone wristband? i am actually using it with the metal one.. the watch is really good..

Rated 4 out of 5 by from Nice Watch Really like the design and look of the watch, it appears to have the capability of a Promaster and a dive watch, wish it was called this in the title or description. The lugs do look odd on the watch and I believe they could have been designed/integrated better to blend into the watch. I really like the watch face, and the band is nicely designed (sure it cant be made in Japan like the watch?). The lume is OK and goes out sooner after you turn off the lights, should have better lume for this style of watch. The time is spot on, 1 second fast after having it on the wrist for 6 days. And really like how the second hand meets the minutes markers perfectly when it moves around the dial, not many watch companies get this right, including more expensive Swiss and German made watches. I purchased the watch on sale through Citizen for under $300. What a great price for a great watch!

Rated 5 out of 5 by from Great watch at a great price. I had bought this watch before and lost it due to a break in the rubber strap. I couldn't wait to purchase it again. A solid watch which you can switch up for dress or casual. I would HIGHLY recommend this great two for one watch.

Rated 5 out of 5 by from Best watch Parents bought this for me as an eagle gift and it's my first nice watch. Love that it switches from the two different bands.
