Deepsea 116660 vs Seamaster Planet Ocean 600m

Both Rolex and Omega are luxury brands of superlatives and with significant corporate history. The models Rolex Sea-Dweller Deepsea and Omega Seamaster Planet Ocean are diver collections of these popular brands.

However, what differentiates the two models from the original collections is that they were developed mainly for extreme water resistance for professional use. Due to their brilliant design, both watches enjoy great popularity even for personal use.

About the Rolex Deepsea

Back in 1926, Rolex introduced the world’s first waterproof watch, the Rolex Oyster Perpetual. The hermetically bolted case quickly became an icon and is now the cornerstone of many other Rolex models. With the introduction of the Submariner diving watch in 1953, history was written and the exploration of the oceans was now possible for the brand. Professional divers had to work at great depths for a longer period of time, however they faced a problem. Helium particles from the breathing air in the diving bells entered the inside of the watch and when the divers emerged back up these particles wouldn’t be able to escape the housing quickly enough. The issue was that these particles could push the watch glass out, whereupon the watch is no longer useful. As a solution, Rolex developed a diver’s watch with a helium escape valve, allowing helium to escape unimpeded when a diver emerges. The high-tech valve is embedded in the case at 9 o’clock and is barely noticeable. 

As early as 1967, this developed enabled maximum water depths of up to 1220 m. Today’s models can easily operate in water depths of up to 3900 m.

About the Seamaster Planet Ocean 600M

Omega also landed a hit with the Seamaster series. Several years before the Submariner, Omega launched the Seamaster in 1948. It quickly became one of the brand’s most popular series. The Seamaster series today has many collections of its own. These include the Seamaster Diver 300M, Seamaster Aqua Terra 150M and of course the Omega Seamaster Planet Ocean 600M.

Omega struggled with finding a solution for pressure equalisation. The helium valve, which was designed for this watch, is found at eleven o’clock and gives the watch a strong recognition value. Unlike Rolex, this valve is not recessed into the case, but protruding. As the name suggests, the Seamaster Planet Ocean 600M dives down to 600m.

The direct comparison in great depths

For the direct comparison we have decided to use the Rolex Deepsea 116660 and the Omega Seamaster Planet Ocean 600 M

Both watches come with the typical, one direction rotatable, diver’s bezel and have minute-marks for the first quarter of an hour. Other similarities include the sturdy stainless steel case, luminescent hands and indices and the date display at three o’clock.

Of course, there are also some visual differences. While Rolex relies on minimalist stick indices, on the Seamaster you can find numbers on 3, 6, 9 and 12 o’clock beside the indices. The overall appearance of the Omega is a bit more bold, on one hand because of the outstanding helium valve, on the other hand because it surpasses the Deepsea by 1.5mm in diameter with its 45.5mm.

The heart of the watches

Probably the most important difference are the inner works of the two watches. Both brands today almost exclusively use complete in-house produced movements.

Starting with the Rolex Deepsea Sea-Dweller, it has the well-known 3135 caliber. This function is seen in many other Rolex model as it is considered by many watch enthusiasts as one of the best automatic movements ever launched. It has no free-swinging parts in the movement, which means that the long-term wear and tear is extremely low. Without any external energie input, this luxury watch will tick for 48 hours.

The Omega Seamaster Planet Ocean 600 M is also a true masterpiece. The development costs of the caliber 8500 are in the high millions and the materials were chosen are all non-magnetic. The power-reserve of this caliber is about 60 hours, so you can take off the watch over the weekend and it will still be accurate on time on Monday.

What is the price policy of these both models?

Another not insignificant difference is the price. Comparing the Rolex Deepsea prices with Omega Seamaster prices, one quickly realises that both models are in different price ranges. For a used, certified Deepsea you pay between 9.000-10.000 € whereas the financing of a vintage Omega Seamaster Planet Ocean is already possible from 3.500 €. Of course with Rolex you not only pay for an outstanding watch, but also for the company’s many years of history and the prestige that the brand brings with it. The wristwatch with the crown is for many still the undisputed leader among the timepieces.

The design of the Rolex Deepsea and the Omega Seamaster Planet Ocean 600M are very different. The Rolex Deepsea comes with a stylish black ceramic bezel, while the Omega Seamaster Planet Ocean comes in many different colours and designs. The diversity of the Planet Ocean is also reflected in the available complications of the movements. The Rolex Deepsea was always made as a classic three hand watch. The Omega Seamaster Planet Ocean is even available as a chronograph version.   

An evaluation of the comparison is difficult and comes down to personal preferences. However, both models are at the top of the range and will definitely guide you on your next adventure.
