Oceanica is a brand new microbrand to hit the scene in 2018 with their first release dubbed the “REEF”. It is a tool dive watch with some exceptional water resistance and certainly pays tribute to vintage seiko dive watches.
The 44MM in diameter cushion case is certainly extremely comfortable on my 6.5 inch wrist with the rubber 20MM dive style strap supplied. It is also comprised of 316L surgical grade stainless steel. The sides are highly polished and I do not see any mistakes there and looks fairly good for a $300 dive watch. The tops of the lugs and case are finely brushed and keep in tune with the style of dive watch seiko produced in the 70s. The caseback is signed “OCEANICA” with their really cool and detailed shark logo and is finely polished as well.
The Reef is equipped with a Seiko NH35 automatic self winding caliber. This movement is a dependable and trustworthy workhorse. I have experienced over 100 watches during my time with this caliber and not once have encountered a technical issue. This model is keeping around +4 seconds a day consistently which is superb! The movement has hacking, hand winding, and 40 hours of power reserve while 24 jewels reside under the caseback as well. This is a great choice of movement and I am glad they went with this over a Miyota 8 series because those for the most part are god aweful movements.
The dial on the Reef is fairly simple and stays true in the historical aspect of the Seiko 6105 dive watch. We get our stop light style seconds hand, applied lumed markers with C3 SuperLuminova. We also get a beautiful Domed Double Anti Reflective coated genuine sapphire crystal. The Reef logo is printed to look vintage as it is semi faded in a way and I think it matches the black/red oceanica logo just fine. We have a date aperture at 3:00 with quicket and is certainly legibile. The lume is spectacular on this model and I was not surprised because C3 superluminova is bright and does the job well! On top of this sapphire resides the 90 Click unidirectional dive bezel with aluminum insert and lumed pip.
Now here is the great part about Oceanica as a value oriented company. The watch comes supplied with a great robust and flexible rubber 20MM strap with polished 316L hardware. Now heres the kicker, they also come with one of those high end luxury seatbelt style NATO straps for free. These straps cost about $25-$30 USD from competitors using the same exact nylon and strap. I thought this was really nice of them to do this and the strap looks and feels great on this 44MM case.
Furthermore my fellow Watch Addicts, this watch certainly plays a role in my collection as a tribute to the past and replaces my need to buy a Seiko 6105 which will have tons of problems down the road without replaceable parts, and cost me almost $2,000 USD. The watch is comfy, is great for everyday wear, and fits like a glove. I reccommend you check this one out fairly quick if you have an interest as Oceanica only produced 50 of these pieces for their first run hence “Limited Edition” printed at the 6:00. You can check out my full video review on YouTube below as well. Be well my friends!
The main component of a mechanical movement is the mainspring, a spring that gradually unwinds and transmits energy. A mechanical watch will keep accurate time despite requiring winding up if it's manual. ... Inside an automatic watch sits a small weighted rotor that has to oscillate in order to wind the mainspring.
