Like the Rolex Submariner, the Rolex Sea-Dweller DEEPSEA is an elegant but extremely robust customer.

Rolex claim that the Sea-Dweller has come to life as the result of pushing the boundaries of what is possible to the limit. Okay… so it’s a cliché but is it true?

Features of the Rolex Sea-Dweller DEEP SEA

• Time and date functions.
• Waterproof to an incredible 3,900 meters (12,800 feet) through Rolex’s patented Ringlock System (a nitrogen alloyed stainless steel pressure retaining ring that protects the the crystal and case back).
• Like the Oyster Perpetual Submariner, the Rolex Sea-Dweller DEEPSEA also uses corrosion resistant 904L steel in its construction.
• Domed sapphire crystal.
• Titanium alloy case back.
• Stainless steel helium valve.
• Triplock winding crown.
• Unidirectional counterclockwise rotatable bezel.
• Highly visible luminescent blue markers on the dial, hands and bezel.
• Robust and reliable chronometric prescision movement that is extremely resistant to magnetic fields and shocks.
• The Rolex Sea-Dweller DEEPSEA is certified as a chronometer by COSC (Switzerland’s Official Chronometer Testing Institute).
• 904L steel strap that can be adjusted to fit over neoprene diving suits up to 7mm thick.

The Sea-Dweller DEEPSEA is another superb Rolex watch that can be enjoyed by divers who are willing and able to invest in such a timepiece. In terms of functions, the Sea-Dweller is not packed with a multitude of tools and widgets: a dive computer this certainly is not. However, as a diver’s timepiece the Rolex Sea-Dweller is the bees knees.

The Most Robust Rolex to Date?

The Rolex Sea-Dweller has to be a contender for the most hardcore diving watch on the planet. Water proof to an incredible 3,900 (12,800 feet) and super resistant to shocks and magnetic fields, recreational divers will find the Rolex Sea-Dweller practically indestructible. As such it may be a “sledge hammer to crack a peanut” scenario for shallow water divers… more likely the Rolex Sea-Dweller watch will appeal to commercial and deep divers. Of course, if you can happily justify the list price of the Sea-Dweller watch then it can of course be enjoyed by any diver out of the water too.

The helium valve will protect the Sea-Dweller from damage for professional divers who have to use underwater pressurised caissons at depth where helium gas mixtures are used: on ascent the valve will ensure that the watch remains undamaged after a stint in such an environment.

Rolex Sea-Dweller DEEPSEA Review Summary

Rolex Sea-Dweller DEEPSEA watches are, like all Rolex watches, elegant and extremely accurate. It is beautifully finished device that is certified by COSC as a chronometer and is quite literally a stunning watch… assuming you have money to burn.

The Rolex Submariner is not a watch that most mortal recreational divers would ever consider as it is an expensive timepiece. So why is the Submariner so pricey and what are the features that make it worth the expense?

This review of the Rolex Submariner aims to answer these and other questions about this highly prestigious range of watches.

Notes About the Rolex Submariner Watch Range

In the main, the Rolex Submariner comes in a 3 different models:

• Rolex Submariner 40mm in yellow gold
• Rolex Submariner 40mm in rolesor
• Rolex Submariner 40mm in steel

The yellow gold Submariner 40mm is constructed in 18ct yellow gold, has a blue dial and a blue rotating bezel as well as a fliplock bracelet. The rolesor version is composed of steel and 18ct yellow gold but has the same color features as the yellow gold model. The 40mm Rolex Submariner in steel has a steel bezel and strap and a black face.

N.B. Throughout the years Rolex have also released a number of special edition Rolex Submariners, with different colorations and metal build combinations, many of which are highly valued by collectors. However, this Rolex Submariner review only focuses upon the models available from the current Rolex collection.

Main Features of the Rolex Submariner

• Waterproof to 100 meters (330 feet).
• Unidirectional bezel.
• Highly luminous markings on the hands, dial and bezel.
• Hyper effective triplock winding crown that seals water out.
• Perpetual rotor makes Rolex Submariner watches self winding.
• Highly accurate Rolex Oyster movement built to last a lifetime.
• Mechanism constructed of 904L steel (a corrosion resistant, stainless-steel alloy).
• Calendar function.
• COSC Certified by the Swiss Official Chronometer Testing Institute.
• Highly elegant and recognizable design.

The Rolex Submariner is recognized in its own right as being one of the finest timepieces known to man. It is owned by many people who have never dived simply for its reliability and elegance. However, divers can take advantage the benefits that this beautiful watch has to offer above and beyond the aesthetic.

The Rolex Submariner 40mm range is designed to withstand massive pressures. It is guaranteed waterproof to depths of 100 meters/330 feet (although in fairness it will be waterproof beyond this point). Its triplock winding crown, which incorporates 3 gaskets, literally screws down like the hatch on a submarine making the Submariner impervious to pressures of 500 bars (equal to 0.5 tons per cm2).

The Submariner also includes Rolex’s ground breaking perpetual rotor mechanism: a mechanism that was invented by Rolex in the early 1930s. The perpetual rotor enables the Submariner to run continuously as the wearer’s wrist movements wind the mechanism.

Much of the Rolex Submariner’s parts are built using a stainless steel alloy known as 904L steel. 904L steel is corrosion resistant and highly durable making it tough enough to take on any diving environment.

In terms of time functions, Rolex watches are famous for their accuracy. The Submariner maintains this leagcy of near perfect timekeeping due to the high quality manufacture and materials of its moving parts.

Its unidirectional bezel provides you with a tool for measuring elapsed time while diving, whilst vibrant luminous markings on the hands, dial and bezel ensure that your timekeeping is not hampered by darker environments.

Rolex Submariner Watch Review Summary

Reliable, robust and accurate, the Rolex Submariner watch is a truly extraordinary timepiece for the diver who can afford it.

The Omega Seamaster watch range. It’s good enough for James Bond… could it be good for you too?

Background on the Omega Seamaster Watch

Like the Rolex Submariner, the Omega Seamaster watch has become a classic diver’s watch. The Seamaster began its life in 1948 with the manufacture of the Omega Seamaster Standard and Chronometer ranges. However, in those days the Seamaster was really little more than a waterproof dress watch… it was certainly not a hardcore diver’s watch. It was not until the 1970s that the Omega Seamaster became more dive-centric.

During the 1970s the Seamaster was built to withstand serious depth as well as provide chronograph functions, rotating bezels and high-vis luminous dials to make them it easy to read underwater. In 1993 the Omega Seamaster Professional (a.k.a. the Omega Seamaster Pro) was launched. The Seamaster Pro is a model of style and substance for divers: it can be taken down to 300 meters (way more than necessary for recreational diving) and offers a host of useful functions for any diver.

The Omega Seamaster Professional Diver’s Watch

The Seamaster Pro is commonly known as the Seamaster 300m, due to its depth capability. It is available in quartz and automatic movements with versions for men and women. The men’s Omega Seamaster Professional comes in two models:

• One has the classic 1993 “skeleton hand”;
• the other has thicker hands known as the “GMT style”, which was released in 1998.

The Seamaster Pro Diver and James Bond

The Omega Seamaster Professional Diver is one of the most popular watches in Omega’s collection. This is thanks, in no small part, to the James Bond movie franchise. The Bond character wore Omega’s Seamaster for the first time in 1995 in the movie Goldeneye. This brought not only the watch to public attention but launched Omega’s public profile enormously. The Omega Seamaster Professional watch is still appearing in Bond films.

Primary Features of The Omega Seamaster Pro

• Water resistant to 300 meters (1,000 feet).
• Screw-in caseback, screw-down helium release valve and screw-locked crown.
• Rotating bezel.
• Luminous hands.
• Self winding movement (includes 44-hour power reserve for when the Seamaster is not being worn).
• Chronometer.
• Highly accurate timekeeping.
• Date window.
• Scratch resistant sapphire crystal.
• Stainless steel case with rhodium-plated strap.

Omega Seamaster Review

The Omega Seamaster watch is a near flawless example of watchmaking on any level. It is a highly attractive timepiece that sits easily on the wrist of anyone be they a diver or not. It is as a diver’s watch though that the Omega Seamaster Professional really comes into its own.

The Seamaster is extremely durable and tough (to 300 meters) and is highly visible to read underwater. You never have to worry about its batteries failing due to its self-winding movement and above all it is a highly reliable piece of equipment.

Its black face and luminous hands and markers make it very easy to read in dark and murky conditions, while its black aluminum rotating bezel with silver coloured ten-minute markers enables you to clearly monitor dive times.

Quite simply, the Omega Seamaster watch range is awesome… but the Seamaster Pro is sublime. It is a fairly expensive watch to own, but by purchasing an Omega Seamaster watch you are investing in something that will potentially last you a lifetime.

Scubapro’s Titanium Diver’s Watch is a very nice underwater timepiece.

The Scubapro Titanium has a 25-jewel Swiss-made mechanized movement that is protected by a water-tight (to 700 meters) solid titanium case.

The Titanium is a kinetic style watch meaning that it is wound by the natural movements of the wearer’s wrist… so you will never need to change batteries underwater!

Main Features of the Scubapro Titanium Diver

The Scubapro Divers Watch has the following specifications:

• Highly luminous dial and hands
• Water resistanance to 700ft
• Swiss movement
• Scratch-resistant crystal glass face
• Magnified date display
• Engraved screw-type case back
• Strap exchanging tool
• Sporty black backup strap
• and titanium all over the place!

Scubapro Divers Watch and Titanium

This particular watch is well named as it comprises multiple titanium components. It has:

• a solid titanium machined casing
• a screw-down titanium crown
• a rotating titanium bezel
• and a titanium strap.

Because the casing, crown, bezel and strap are all composed of titanium and the face cover is crystal glass, the Scubapro Titanium is very light and practically immune to damage.

Usability

As you would expect from any good dive watch, the dial and hands are easy to see.

Firstly the face of the watch is not over fussy (always a good usability design feature) and the important parts of the hands and dial are marked with a highly luminous paint making the Titanium a very easy timepiece to read underwater.

The Scubapro Titanium is also resistant to around 700 feet… more than enough atmospheres for your average recreational oxygen divers… in fact pretty handy for commercial deep divers too!

An understated but great diver’s watch, the Scubapro Titanium is a little nugget.
