Oceanus Watches

Oceanus Support 

All current information is available at www.oceanus-us.com. The direct Oceanus Help Line is [phone].

Hamilton reps will ask for the model number. That number can be found on the back of the watch. It is the letters OCW- followed by numbers.

If it is an Oceanus watch that does NOT begin with the OCW, only OC, Hamilton will provide support, otherwise, give the customer the Oceanus Support phone number listed above. The module numbers are on the back of the OC models, the same as all other Casio models, and if necessary you can search the Casio site for the manuals.

As the model numbers are constantly changing, we can not give you a complete list, but the guidelines above will always apply.
