Omega Speedmaster Moonwatch Professional 42mm 311. Watch Review

Omega goes above and beyond to ensure that they leave no stone unturned when it comes to the durability of their watches. Their Seamaster Diver watch series has proven to be one of the best diver’s watch series in the luxury watch market.

Omega watches are the definition of versatility; they work with precision and accuracy in the depths of the ocean as well as on land. To say that the Omega Moonwatch Professional 42mm 311. is “out of this world” is no overstatement; Omega watches have been worn by astronauts on every lunar journey since 1969.

Timepieces in the Speedmaster Moonwatch collection have long been associated with strength, durability, precision, and accuracy. The new pieces from this collection offer brilliant innovation in both design and specification. One of the best pieces from the Speedmaster Moonwatch collection is the Omega Moonwatch Professional 42mm 311.

The Design:

From the minute your eyes land on the Omega Moonwatch Professional 42mm 311., you will be drawn towards the elegance of the design. Even though the diameter of the case is 42mm, the watch has been crafted to not look thick and bulky on the wrist. The dome is offered with either Hesalite crystal or sapphire glass.

The watch comes in a purpose-built box with both a nato strap and an astronaut strap, which can be interchanged with the watch’s stainless steel bracelet. This watch case is also stainless steel, and the steel on steel design adds to its sleekness and elegance. It has a black dial with a second sub-dial and two recorders. Even though it is an astronaut's watch, the look and grace of this timepiece allow you to pair it with suits on dressier occasions. The watch also has an attached tachymeter to further increase functionality. The luminous white hands of the watch offer beautiful contrast with the black dial.

The Specifications:

When you buy the Omega Moonwatch Professional 42mm 311., you are not just buying a timepiece- you are buying a small part of history. From winning the title of the professional watch to be used during NASA missions, to winning the “Snoopy” award for potentially saving the lives of the crew of the Apollo 13 mission, Omega Moonwatch Professional watches have proven to be extraordinary. Although the classical design of the original Moonwatch has been carried on over the years with only a few alterations, the specifications of the Moonwatch have changed over time to make it more precise and accurate.

The Hesalite crystal on the dial is an amazing feature as it offers more shock-resistance and protection than standard sapphire crystal. The piece is also water-resistant up to an impressive 50 meters and comes with a 48 hour power reserve. The watch is extremely precise and has a frequency of 21,600 beats per hour.

The Omega Moonwatch Professional 42mm 311. was designed with such attention to detail and perfection that it was able to pass all of NASAs quality checks and tests. If it is amazing on the moon, you can be sure that it will make head turns when you wear it on the ground.
