Quartz movements are much thinner than automatics. So from a watch making standpoint it’s a lot easier to make a thin watch with a quartz movement.

To make the list, the watch has to be 12mm thick or less.

As usual we are focused on dive watches here at The Dive Watch Blog. So that means they are all water resistant to 200 meters, have a screw down crown, and feature a uni-directional rotating bezel. All dive watches should have these features at a minimum.

Around the internet you will see many people, whom know very little or nothing about dive watches, recommending and posting lists about the best dive watches, etc, etc, and many of these watches on the list are water resistant to 50 or 100 meters. Those are probably fine for splashing around in a pool, but not for scuba diving.

If you intend to dive with the watch you are purchasing you want a 200 meter water resistance rating. Anything less will not do.

Now if you don’t dive and really have no intention of going in the water with the watch you are looking for, then there are probably a lot of other thin quartz watches out there for you.

If you are interested in the difference between a quartz movement and an automatic movement you can read all about that here.

Here are 7 thin quartz dive watches worth buying.

Neymar 300M Diver – 10.3mm

Oh Neymar, why did you have to discontinue this watch?? This Neymar was originally available when I wrote this article. I still have mine, and it’s a great quartz dive watch. It is very thin at only 10.3mm. I really enjoy mine and have received many compliments on it. I wear it with a suit often because it fits so well under the cuff of my dress shirts. It has a stainless bracelet.

You can sometimes find them on ebay, so for the time being I will leave it on this blog post. It’s a great option if you are looking for a slim quartz diver if you can find one on the used market.

Seiko Prospex Quartz – 12mm

Seiko is well known for making affordable, good quality dive watches. The Seiko Prospex line continues this tradition. Nearly all of the watches in the Prospex line are automatics, and are thicker. They still make this one in a thin quartz model. It comes directly from Japan.

The Seiko Prospex Quartz is ISO Rated to 200M, this is a proper dive watch. It features a quartz movement with solar charging so you don’t have to replace the battery. The dial is actually a little solar panel. A normal quartz movement requires a battery change every two or three years. It also features a sapphire crystal. This watch will last for years of good service.

Tag Heuer Formula 1 Quartz – 12mm

Tag Heuer is a legendary watch maker and is at the top of a lot of people’s list as far as quality and heritage, as it should be.

WR to 200M even though it doesn’t say so on the dial, this Tag has a stainless case, but also features a titanium bezel. The bezel does tend to get knocked around more than the case because of its placement, so that is interesting to me. At 41mm wide and only 12mm thick, this is going to be a sweet spot for a lot of people and won’t look too small or too big on your wrist. That’s for most people. The Tag will be just as well at home under a business suit as it is on the ocean at 100ft deep.

Casio Duro (Marlin) – 12mm

The Casio Duro is not only one of the thinnest dive watches on the market, it is also the most insexpensive. I have scoured the marketplace, and consistently the cheapest dive watch out there with a 200M water resistant rating. As of this writing you can pick one up for around $55 USD.

For that price, if you are looking for a durable dive watch, look no further. Now, it’s pretty basic and sports the Casio brand name. This is not a Rolex or Omega by any means, but then again you’re not shelling out several thousand dollars for it either, so if you slam it into something or get some paint or oil on it you won’t be too concerned.

I like the Casio Duro for what it is, a simple dive watch that I can wear while working on diesel engines, painting or doing general boat maintenance. I occasionally wear it out and about, it is thin, light and generally unobstructive. It is not trying to be a tool diver or anything like it. It’s a simple slim dive watch that is easy to read and won’t break the bank. I think I’ve had mine for five years with no issues.

Luminox Pacific Diver – 12mm

Luminox is really a military inspired watch brand, they actually make special watches with military unit insignia on them. The Pacific Diver is far from that style of watch. To me this is a more traditional dive watch.

The Luminox Pacific Diver featues a sapphire crystal, WR to 200M, with a date complication and a very nice steel bracelet. The lume on the watch is actually tritium which will last for decades and doesn’t have to be charged with a light source. Although it doesn’t necessarily look like something worn by a military unit, it’s tough enough to go into battle.

Longines HydroConquest Quartz 39mm – 10.2mm

The Longines HydroConquest comes in multiple sizes. Many watch makers are doing this now to appeal to a broader segment of the market. Gone are the days were dive watches were big behemoths adorning your wrist. Those watches are still out there, but it is not uncommon for a watch maker to offer two or three sizes so you can find one to fit your preference.

The 39mm variant of the HydroConquest is one of the slimmest watches on this list. It’s also one of the nicest, most refined watches on this list as well. It has just about everything you want in a dive watch, sapphire crystal, WR to 300M, beautiful bracelet and clasp.

Citizen Promaster Eco Drive – 12mm

First of all, Citizen makes lots of Promaster dive watches, so there is a lot of variation in there. The Promaster Eco Drive is one of their most popular models, if not the top seller of the entire lineup. It features a solar powered quartz movement that should give you years of service with no need to replace a battery. Some of these Promasters are huge watches, so if you are after a thin quartz model make sure you are getting the right one.

I actually own the Promaster Eco Drive and I use it a ton. I pair mine with a nylon strap, but a silicone strap would work great as well. The original strap it came with is a little stiff for my liking. The bezel and lume work great on these watches. I really can’t say a bad thing about them.

Invicta Pro Diver 8932 – 11mm

Invicta makes a lot of Pro Diver watches. At this point there are definitely dozens of models, some of them quartz, and some are automatics. This is the thinnest one in their lineup. For a sub $100 USD dive watch, you get your money’s worth here. It’s getting hard to find a dive watch under the $100 mark anymore.

If I had to choose between the Casio and the Invicta, I would probably go with the Casio. I don’t like the branding all over the Invicta, and of the one’s I’ve seen the bezel is much nicer on the Casio. But, if you like the look of the Invicta better, pick that one. This comes down to personal preference. The Invicta definitely looks more expensive.

If the reason you are looking for a thin dive watch is you have a small wrist, you should read my post – 21 Small Wrist Dive Watches, you may find one in there that will work for you.
