Omega Mens Seamaster Aqua Terra Railmaster Automatic Watch 2503 52 00

Set sail with confidence and style to points unknown with this classic Omega Aqua Terra stainless steel men’s automatic chronometer watch, part of Omega’s Seamaster line. This highly accurate timepiece is as comfortable negotiating deals in the boardroom as it is navigating the breaking seas. Definitively masculine in design, it features a mid-sized, round silver stainless steel watch case with a rhodium-plated finish that blends brushed and polished surfaces and measures 38mm (1.50 inches) wide.
It features a slightly raised, highly polished bezel that frames a black dial background with Dauphine hands, a mix of silver tone triangular dial markers and Arabic numerals (at the quarter hours), and small minute indexes. Other features include a scratch-resistant and glare-proofed domed sapphire crystal, and water resistance to 150 meters (500 feet). It’s completed by a silver stainless steel link bracelet band that offers polished highlights, which is joined by a deployment-clasp-with-push-button clasp.
Originally created in the 1750s, the first chronometers were clocks that were accurate enough to calculate the longitude of a ship’s position. Today, the chronometer label is bestowed upon timepieces that have undergone precision tests and received a certificate from the official COSC (Control Officile Suisse de Chronometers) regulatory organization that rigorously tests and certifies (or fails) watch movements for chronometer status.
Automatic Watch Movement
An automatic watch is self-winding, and its movement has a reserve that must be at least partially filled prior to being worn. This is done by shaking and winding the timepiece manually. In order for an automatic timepiece to keep a reserve, it must be worn daily for 8 hours of active wear. This watch as a 44-hour power reserve.
The Omega Story
The Omega watch story begins in 1848, when founder Louis Brandt began hand assembling key-wound precision pocket watches from parts supplied by local craftsmen in his principality La Chaux-de-Fonds, in the northwest corner of Switzerland. However, the Omega name didn’t appear until 1894, after Louis Brandt had passed away and his watchmaking traditions were taken over by his sons, Louis-Paul and Cesar Brandt. Omega watches have long been associated with glamorous screen and sports stars–the Omega Seamaster is famous for being the watch of choice for James Bond–with current ambassadors including Pierce Brosnan, Nicole Kidman, tennis player Anna Kournikova, and swimmers Michael Phelps and Ian Thorpe.
But Omega is more than just a fashionable watch. In 1965, the Omega Speedmaster chronograph was “flight-qualified by NASA for all manned space missions” as the only wristwatch to have withstood all of the U.S. space agency’s severe tests, including passing grades for extreme shocks, vibrations, and temperatures ranging from -18 to +93 degrees Celsius. The greatest moment in the Speedmaster’s history was undoubtedly 20 July 1969 at 02:56 GMT, when it recorded man’s first steps on the Moon’s surface as part of the Apollo 11 mission. Today, Omega is known for its rigorous testing of new movements, cases, and bands. Each new Omega movement is tested on the wrist in existing Omega models, while various laboratory tests are conducted to determine temperature-resistance, shock-resistance and vibration-resistance.
User Ratings and Reviews
1 Star Not the watch I thought
I was looking for a black face Omega Agua Terra and saw this watch at Amazon. Unfortunately model 2503.52 is a Omega Railmaster and while it is part of the Seamaster line it is not an Aqua Terra. There was nothing outside of the model number that stated it was a RailMaster. The watch came from Amazon and when I returned it I was shocked to find that Amazon Customer Service was going to hang on to my money for over 30 days – thus I was paying interest with the credit card company. Even more unfortunate is that this is company policy on any thing listed as “jewelry”. I’m still waiting for Amazon to process my return.
Oh- if you look at the ad for this watch now it states it is a “Railmaster” on the site.
I still want the Aqua Terra, but would caution any buyer from purchasing any watch from Amazon as you will be waiting a long time if you need to return it!
5 Stars This watch is NOT an Aqua Terra!! Buyer Beware!
Visit the official Omega Watch web site and you will see that Omega Reference 2503.52.00 is a Railmaster Chronometer NOT an Aqua Terra! I cannot locate a link to report this mis-identification to Amazon anywhere. Maybe someone who reads this and knows how to notify them will do so.
If you type in tinyurl dot com forward slash 6h6vgw, it will take you directly to the Omega web site where this item is detailed.
Omega is a quality product and Amazon is a quality seller with awesome prices! You can’t go wrong, just make sure you know what you are buying.
I will be ordering an Omega Aqua Terra soon as a gift and I plan to buy it right here on Amazon.
5 Stars Can’t go wrong with Omega
It’s a fantastic watch with a classic look and feel. Not as big as most of the seamaster line, it looks great against a good suit or tux. Even though it is smaller it has a more refined feel than a Tag, Edox, or Breitling.
-Cheers
