If you’re looking for the largest dive watches that are currently roaming the seven seas, you’ve come to the right place. Every watch on this list is a legitimate dive watch, they nearly all carry the ISO 6425 rating or are way overbuilt. These are the largest dive watches plying the oceans.
There are a few features that the watchmakers have included on many of these watches (not all of them) to make such a huge watch work on someone’s wrist. The first feature is that although they have a huge case diameter, the lug to lug is short enough that you don’t necessarily have to have a huge wrist to wear them. Even though the case diameter plays a role in the fit on your wrist, the lug to lug measurement, which is where the strap or bracelet attaches, also plays a critical role in how it wears on the wrist. The other feature is a lot of these watches are made from titanium, which makes them considerably lighter than their stainless counterparts.
That said, these watches are still huge. These are sport watches after all, none of them is going to go under a shirt cuff, and they are all going to make a huge statement. They’re designed for getting out there and exploring, not sitting in the office.
Marathon 46mm Jumbo
Case Size: 46mm Case Thickeness: 18mm Water Resist: 300M Movement: Quartz Crystal: Saphire
Marathon has been making search and rescue and military watches for decades. Although they have slight variations, they mostly look alike and have different dials, movements and sizes. This particular model is referred to as the JDD, or Jumbo Day Date for obvious reasons.
The JDD features tritium gas tubes instead of lume. This is common on many military watches. The tritium always glows and does not need to be charged with a light like luminous paint does.
Here is the listing for the Marathon Jumbo on Amazon.
Citizen Promaster Aqualand 200M Depth Meter
Case Size: 53mm Case Thickeness: 17mm Water Resist: 200M Movement: Quartz Solar Crystal: Mineral
Citizen has been making depth guage dive watches for a few decades. They launched the original Aqualand with a depth gauge in 1985 and it was an instant hit. People still love that watch all these years later. Like any good company, Citizen didn’t just rest on their laurels, they have been upgrading and coming out with new models every several years. Nowadays they have a few Aqualands that have depth gauges on them, but this is the pinnacle right now.
The Aqualand 200M Depth Meter has an eco drive solar powered movement as well as a power reserve gauge. At 53mm the case is enormous. As far as price, it’s one of the most reasonable on the list, you can pick one up for around $700.
Here is a link to the Amazon listing for the Citizen Aqualand Promaster.
Blancpain Fifty Fathoms X Fathoms
Case Size: 55mm Case Thickeness: 24mm Water Resist: 300M Movement: Automatic Crystal: Sapphire
Blancpain was the first watchmaker to actually make a dive watch, and they’ve continued their innovation and expertise moving forward, the X Fathoms is the current pinnacle of that innovation. This 55mm monster is made from titanium, so it’s not super heavy for the size.
Aside from the integrated depth meter, the X Fathoms has a five minute decompression timer located between the 10 and 11 o’clock indices. If you are a diver you know how important decompression and/or safety stops are. I’ve never seen this on a dive watch before.
the X Fathoms is near, or even at the pinnacle of dive watch innovation, craftsmanship and design.
Breitling Superocean 46
Case Size: 46mm Case Thickeness: 16.85mm Water Resist: 2000M Movement: Automatic Crystal: Sapphire
The Breitling SuperOcean is trying to be one thing and one thing only, a super clean looking, simple, easy to read dive watch. They’ve done this on purpose to have a dive watch that is super simple without any complications or unnecessary marks. I think they’ve achieved the goal with an accurate Chonometer movement to power it. Sometimes simplicity is the best policy.
Here is the Amazon link to the Breitling SuperOcean 46.
Omega Planet Ocean Ultra Deep
Case Size: 45.5mm Case Thickness: 18.1mm Water Resist: 6000M Movement: Automatic Crystal: Sapphire
You will never dive deeper than this watch can handle. It’s physiologically impossible.
The Ultra Deep is ISO rated for saturation divers, has a case made from Omega’s proprietary Omegasteel, and is a Master Chronometer. It’s almost like Omega has a mad scientist division that came up with this watch because they threw everything at it. The Ultra Deep has hands made from white gold.
This isn’t the biggest or most expensive watch on the list, but I personally think it’s the baddest.
Citizen Aqualand 1000M Professional Diver
Case Size: 53mm Case Thickness: 22mm Water Resist: 1000M Movement: Quartz Solar Crystal: Sapphire
The Citizen Aqualand 1000M Pro Diver is a gigantic watch at 53mm wide and 22mm of case thickness. However, due to it’s titanium construction it is incredibly light for its size.
You would think with a 53mm wide case you would need a huge 8.5 inch wrist to wear this monster, but due to the design the lug to lug width is less than the 53mm case size, it is incredibly wearable for maybe down to a 7.25 inch wrist. It’s still huge, you’re not getting it under a shirt cuff.
It’s solar powered and has a reserve indicator in the 9 o’clock position. This is a huge tool diver.
Seiko Prospex Tuna
Case Size: 52mm Case Thickness: 13.4mm Water Resist: 200M Movement: Automatic Crystal: Sapphire
Seiko makes a lot of Prospex watches, and there are actually several versions of the “Tuna.” One even has a digital complication. It was made famous by Arnold Schwarzenneger wearing it in Predator, that one is called the “Arnie” for obvious reasons.
They all come standard with an ISO 6425 rating and a Seiko automatic movement. They retail for around a thousand bucks.
Here is the Seiko Tuna Amazon listing.
Oris Pro Diver GMT
Case Size: 49mm Case Thickness: 15mm Water Resist: 1000M Movement: Automatic Crystal: Sapphire
Oris has another huge Titanium diver on the list. This one is the only GMT on this list, it’s way overbuilt and water resistant to 1000 meters, which is way deeper than you’re ever going to go. You can get it with a bracelet or rubber strap. There is a small second subdial at the 9 o’clock marker as well as a date complication at 3 o’clock. The Pro Diver GMT has a 38 hour power reserve.
Tissot Seastar 2000 Professional
Case Size: 46mm Case Thickeness: 16.25mm Water Resist: 200M Movement: Automatic Crystal: Sapphire
To start off, the Tissot boasts a very long 80 hour power reserve. It’s antimagnetic, shockproof and temperature resistant. The only complication is the date at 3 o’clock. At 46mm it’s by far not the biggest dive watch on the list, but that should still be big enough for just about everyone, and this could even work if you have a wrist on the slender side. It also features an exhibition caseback, and ISO rating and a helium escape valve if you’re a commercial bell diver.
Of all the monster watches on this list, I think the Seastar has the most unique and beautiful dial. Of course beauty is always in the eye of the beholder.
Here is the Amazon listing for the Tissot Seastar.
Omega Seamaster Proplof
Case Size: 55mm Case Thickeness: 18.3mm Water Resist: 1200M Movement: Automatic Crystal: Sapphire
The Proplof is one of the largest and definitely the most unique watch on this list. The original Proplof was introduced in 1970. The current model was reintroduced in 2016. Proplof is short for plongeur professional (French) or professional diver. The Proplof features a Master Certified Chronometer, a sapphire bezel insert and a helium release valve.
The bezel is actually bi-directional, but the large button at the 2 o’clock position locks the bezel. The automatic helium release valve is located at the 4 o’clock position. The Proplof also features an exhibition caseback so you can see the beautiful Master Chronometer movement. Omega’s dive watches continue to impress.
