Dive watches have come and gone throughout history, with Rolex and Omega being the most well-known. Many people wear Submariners and Seamasters, and some claim it’s the ideal type of watch to wear. However, the Japanese Domestic Market likes to argue otherwise.
Seiko watches are a popular choice to write about, mostly confined to Seiko’s Prospex series. But what made the Prospex so desirable?
Prospex stands for “Professional Specifications.” It’s Seiko’s contribution to the professional world, where people expect nothing less than the finest timepieces.
In the 1960s, the prevalence of scuba diving was on the increase. We know how important it was for every diver to time their dives, and the impact it had on the horological business was game-changing. As such, dive watches became exceedingly popular. Every watchmaker internationally competed to create the best, and the result was the 6217, the first Seiko diving watch in 1965. It was Seiko’s initial foray into the realm of “high-end” professional dive watches. Subsequently, it helped make Seiko dive watches as iconic as they are today.
Ever since, Seiko has been producing a range of timepieces devoted to diving. From low-cost quartz timepieces to higher-end automatics, there’s something for everyone.
Prospex timepieces are not to be mistaken for Seiko’s traditional mechanical wristwatches. These are far from inexpensive, and their build quality is comparable to that of a Rolex. A high-end precision device from a company known for producing low-cost quartz. This is only scratching the surface when it comes to construction quality. Prospex is known for its modern technologies.
In respect of diving watch development, Seiko’s Prospex is the main pioneer. For example, Prospex is the very first diver watch to include a titanium casing instead of steel. Also, the first to utilize a quartz movement in a pro dive watch. The first to have a ceramic shroud for deep-sea dives. And the first one to employ a combination analog-digital watch, including an alarm. Finally, the timepieces are driven by Seiko’s own in-house movements. These are widely regarded as among the highest quality in the industry today.
Not restricted to diving watches, the Prospex line provides a range of precise timepieces. The Prospex series includes automatic and quartz movements. Also, analog and digital displays. The majority of people can’t distinguish between a regular Seiko and a Prospex timepiece.
Though collectors didn’t receive all Prospex models well, each new release had a different reaction. Some were successful, and others were not. But whichever did become popular was likely a diver’s piece. Seiko has gained a deep understanding of diving watch development. Consequently, mistaking the Prospex collection for a diving range is common. Despite this, Prospex remained committed to producing the highest quality products using Seiko’s technology for pros.
Marine Master Professional
Let’s take a look at Prospex’s most famous offering, the Marine Master Professional. Affectionately nicknamed “Tuna.”
So why “Tuna”? Well, the Marine Master has a similar likeness to a tuna can. The Tuna came in a variety of styles – the main differences being the depth rating and movement. And the granddaddy of all, the SBDX011, earned the moniker “Emperor Tuna.” Mostly due to its massive size and 1,000m depth rating
The “Emperor Tuna” houses a highly sought-after movement. A Seiko in-house caliber 8L35 powers it. This is a variation or, to put it differently, an undecorated movement comparable to the 9S55. The 8L35 is a Prospex that has a 50-hour power reserve, date display, hacking mechanism. Furthermore, it has automated winding with an accuracy of +/- 15 seconds every day (that can be adjusted and calibrated). This reliable movement can withstand harsh conditions. There are bells or whistles like see-through case backs… It’s just a basic, long-lasting movement created for the sea.
Overall, the Seiko Prospex, especially the Emperor Tuna, is the best Seiko offers. Everything from the build quality to the movement is exactly what a serious professional desires. It’s a powerful item that can stand up to the strongest of rivals. New pieces are released every year. Revolutionary technology is on the horizon, not to mention the occult-like antique culture that exists now. The Prospex Marine Master will most likely alter your opinion about Seiko watches.
The Landmasters, Fieldmasters, and, of course, those driven by Seiko’s unique Spring-drive mechanism are other noteworthy Prospex pieces.
