Spinnaker Dumas (Review) – The best dive watch so far from Spinnaker

Today we are gonna look at another Spinnaker watch! And I got to say, when I first saw it, I was blown away by the design. I think Spinnaker really outdid themselves with this one. It has something from Omega Ploprof, but with that Spinnaker touch so it isn’t really a homage. The watch is called Dumas and its name is taken from the famed diving pioneer Frédéric Dumas! I won’t go into details about the company as I already have tons of articles on the company explaining the history and everything, so let’s start the review!

The Dumas comes in the same box as all Spinnakers do. Just a cardboard box with cleaning cloth and some instructions inside. The first impressions of the watch were good. I really like that 1970s design it has and that case is crazy! I also noticed that it is pretty heavy, but I like that, I like when you can feel the watch as this one is a proper dive watch! With the watch, I also got an optional mesh bracelet which was really good, but sadly it broke on the first day and it felt quite badly built, so that is probably the only bad thing I have to say about this watch.

The case of Dumas is made of 316L stainless steel. The case is very well machined with nice lines and angles. Spinnaker has grown a lot in the last 3 years making better quality watches and making each new release even better than the last one! The case has a mix of polished and satin-brushed finishes. I really like how the side edges are polished, gives that 70s look to it. The case is 44mm (without crown) wide, the thickness is 15mm and from lug to lug it is 48mm. The watch on paper looks big, but it wears much smaller due to the case design with those non-existing lugs. On top, we have a 120 clock unidirectional bezel with mineral crystal insert that has lumed markers. This is actually the first time I hear that the bezel insert is mineral, rather than being sapphire or ceramic. The bezel has nice, smooth and precise action and it won’t turn on accident. At 3 o’clock we have these beefy crown guards and a screw-in crown with nice Spinnaker logo on top. The crown is very easy to operate due to that nice grip it has. The screw in exhibition case back has some engravings with specifications of the watch. The crystal on the back is a flat sapphire. On the front, we also have a flat sapphire with blue AR coating. The water resistance is 30ATM (300M) which is more than enough to dive, swim with this watch and enjoy all kinds of water activities without any problems.

The dial is very vintage inspired and that big orange minute’s hand and smaller hour hand reminds me of the Omega Ploprof a lot and many other dive watches from the 70s. It does feature bold lumed markers filled with Swiss SuperLuminova. The applied circular markers are very legible, as well as the square date window at 3:00 which has a matching blue date wheel. I like that brands match date wheels with dial colours as many brands don’t do that and to me, it looks weird that dial, for example, is black, but the date wheel is white.  If you look real close, you will also notice the 24-hour markings – which can be useful in some situations when travelling. The lume on the hour markers and hands is pretty legible and lasts pretty long.

The movement that is inside the watch is Japan made Seiko NH35A, which is reasonably well regulated at +15 to +18 seconds a day. This movement is pretty popular in the microbrand world as 50% of watches that are coming out have this movement inside them. It has proven it’s reliability and easiness to service within many years. You just can’t go wrong with Japan made movements from Seiko. It is an automatic 24 jewel movement with 41-hour power reserve and beating away with 21,600 BPH. Spinnaker also throws on top of the movement a customized rotor in black colour. 

The blue rubber strap that came with my watch is pretty good. The rubber is very soft and supple so it will wrap your wrist nicely. On the top, it has this almost waffle-like texture. The tang style stainless steel buckle is signed with Spinnaker logo and matches the finishing on the watch case. On the wrist, the watch wears really well. It is noticeable on the wrist due to big and bold looks and also the weight, but it feels very good on the wrist throughout the day. I have been wearing it for a week straight before I started to write the review and can say that it is a great desk diver! In the summer maybe I will report more on its diving capabilities!

Overall the watch is great. I like the vintage styling and the blue, orange colour mix. I think Spinnaker outdid themselves with Dumas as this is the prettiest diver they have released so far. When it comes to price, I think it is priced pretty good, just at 350$ and for that price you get an automatic movement, sapphire crystals front and back, nice design, good lume, very well made rubber strap and overall great dive watch to add to your collection!
