This is my third oceaneva purchase.Love the quality and the build.Quality of build and attention to polishing are 2nd to none.Several people ask if this is a Rolex and tell them this is titanium and Rolex doesn’t make a titanium model.I also tell them Rolex is a joke compared to the quality and build of these watches for the price.For quality and build ,this is a no brainer.If you have the money to blow buy a Rolex.For the quality and expert craftsmanship buy a Oceaneva

Love this watch. It's my daily driver and only watch I wear. I'll be keeping an eye on what else Oceaneva comes out with. Five stars for sure.
Oceaneva Men's GMT TITANIUM Automatic Deep Marine Explorer 1250M Black Ceramic Bezel Watch
Absolutely love this titanium GMT watch. It's been my daily driver with satisfaction on every detail. Lightweight, accurate movement, sharp looks, comfortable fit, and proper design for deep water. I'll leave another review after I wear it for a year or two (after lots of snowboarding and snorkeling). So far I don't think I'll ever need any overpriced watch brands after this solid watch. Keep up the great work Oceaneva.

Love this my 5th watch from Oceaneva⁉️
Oceaneva Men's GMT TITANIUM Automatic Deep Marine Explorer 1250M Black Ceramic Bezel Watch
Great purchase, especially for the price. The titanium is high grade and makes the watch more comfortable to wear. It's easy to see the time in darkness and the watch has been very accurate. I've had to make no adjustments to time in two weeks.
Oceaneva Men's GMT TITANIUM Automatic Deep Marine Explorer 1250M Black Ceramic Bezel Watch
Lume yellowed/browned less than a year in. Contacted Oceaneva today as bezel still in 2 year warranty. Hopefully this is an isolated issue with my piece and gets resolved. Other than that, great watch, really well made, keeps great time. I swapped out the titanium bracelet for the rubber one, but both are great. Shame about the lume, and I'll share an updated review once I've heard from Oceaneva.

Store owner replied: Thank you for sharing this feedback. We see you’ve had the watch for nearly two years, and we’re happy to help. If you’d like, we can work with you to replace the bezel. Regarding the lume: this typically isn’t a warranty issue. In most cases, discoloration is environmental—often just surface buildup that can be cleaned. A soft-bristle toothbrush with a little mild soap and water usually does the trick. For context, we’ve sold thousands of these models from the same lume batch and have seen 2 similar cases. In those instances, 1) prolonged exposure to high heat and magnified sunlight on a cash dash during the summer for weeks. and 2) regular smoker that used that hand to smoke caused the lume to yellow over time. Modern Super‑LumiNova generally doesn’t develop patina like older tritium or radium; it’s usually environmental rather than material failure. If you’d like, please reach out to our support team and we’ll guide you through cleaning tips or discuss a bezel replacement. We appreciate the opportunity to make this right.
Very nice. My colleague thought Maserati watch. Finishing 👍
Oceaneva Men's GMT TITANIUM Automatic Deep Marine Explorer 1250M Black Ceramic Bezel Watch
This is my second oceaneva and a third coming down the hatch soon . The titanium and size is probably my favorite out of it all . It’s hard to find a decent size watch that isn’t terribly chunky but not too darn small . Titanium is also a tricky color to get right where it doesn’t look cheap and dumb . I think they nailed it pretty well . Definitely one of my favorite lines
Oceaneva Men's GMT TITANIUM Automatic Deep Marine Explorer 1250M Black Ceramic Bezel Watch

This is my first watch from Oceaneva. I got # 00015 I am looking forward 😁 for something new from Oceaneva. Beautiful 😍 watch with amazing lume. I love this timepiece 😍 Great value for the price; sapphire crystal, ceramic bezel, titanium case & bracelet, Seiko automatic movement well done 👌🏻 Oceaneva team. P.S. it would be nice to see that GMT hand is in same color as ceramic bezel like you did with Black Green version. And Pepsi version would be amazing ☺️Would like that there is option for jubilee titanium bracelet. Thank you 😊 Oceaneva team
Oceaneva™ Men's GMT TITANIUM Automatic Deep Marine Explorer 1250M Black Ceramic Bezel Watch
Great watch for a great price! All quality components - sapphire crystal, titanium bracelet and case, Seiko automatic movement. Light weight and doesn't feel as big as it is. It's thick. Comes in a nice box! Only negative is the titanium bracelet is sharp around the edges of the links and kind of digs into my arm.
Oceaneva™ Men's GMT TITANIUM Automatic Deep Marine Explorer 1250M Black Ceramic Bezel Watch

Great experience. My watch was shipped super fast and arrived without any issues. When I had a question about the functionality of the GMT, they answered within an hour and clarified just how the GMT works. This is my first GMT watch and I couldn't be happier with the watch and the experience I have had so far with Oceaneva. The lume is crazy bright! This will not be my last watch from them. AB

Oceaneva Men's GMT TITANIUM Automatic Deep Marine Explorer 1250M Black Ceramic Bezel Watch
the timepiece is exactly as advertized, with the design, quality and presentation (box) is exceptional given the price. Titanium presents a unique experience on the wrist, by virtue of it's lighter weight, yet for those that want a high quality timepiece with a lighter presence on the wrist this is a great watch. (If onthe other hand the preference is for a more substantial feel on the wrist the recommendation should be for a steel version). The GMT function is highly desirable for my specific use, so definitely a bonus.

It's a nice looking watch on the rubber band. I wish the titanium band was a little shinier.
