Omega Seamaster Diver 300m Chronograph Review

The Omega Seamaster Diver 300M model is produced by leading Super Clone manufacturer workshops with a high-tech ceramic case, standard case diameter and high-precision automatic Super Clone mechanism architecture. It is among the most successful 1:1 super clone watch reviews on the market, with its sapphire crystal AR coating glass, original case tolerances and detailed workmanship.

We have written arguably the most detailed and transparent reviews about Seamaster watches on the internet. Now it's time to do the same for the Omega Seamaster Diver 300m Co-Axial Master Chronometer Chronograph.

Omega Seamaster Diver 300m Co-Axial Master Chronometer Chronograph Review

Omega Seamaster has been identified with diving and excitement since its launch; Following the success of the original Seamaster, many Seamaster models were launched.

This is what happens when a successful watch manufacturer like Omega has perfected a watch and the only way to make it better is to add mechanical features to the watch such as a chronometer; This feature gives the watch a stopwatch function.

Let's get to know this watch closely. Although we can find models with rubber straps, two-color bracelets and even 18 carat rose gold cases in this collection, today we will take a closer look at the two most popular models in this series. Let's examine the watch feature by feature, shall we?

Dial

The dial of the Seamaster Professional Diver 300m has always had a very distinctive appearance. Recently, since this collection was given the title of Master Chronometer, the dial now features a laser-engraved wavy pattern. This pattern is currently available on both the new Seamaster Diver 300m Co-Axial Master Chronometer and the Chronograph version of this watch.

Surrounding the dial is a combination of round and stick lume applique hour markers, and polished steel hour and minute hands in skeletal form, bearing lume material for maximum readability in low light conditions.

In the new Seamaster Chronograph models, split seconds are also printed between each seconds marker on the printed seconds ring. This is of course to allow precise time measurement with a chronograph.

There are two secondary dials on the dial. The small running seconds subdial is located at 9 o'clock, while the 12-hour chronograph subdial is located on the right. Both subdials have polished steel hour and minute hands with a small amount of lume filling.

There is a date window at the 6 o'clock position of the dial, controlled by the crown on the right side of the case.

The Omega Seamaster Professional inscription is located at the top of the dial, just below the applique 12 o'clock double stick hour marker. The phrase “Co-Axial Master Chronometer 300m/1000ft” is printed right above the date window at 6 o'clock. Since the dial is made of high-gloss zirconium oxide ceramic, [ZrO2] is engraved on the sapphire glass covering the dial, just below the central hour and minute hands.

CASE

The cases of these two models use a combination of polished and brushed stainless steel. The ears are finished with polished finish on the outer angles and brushed finish on the front surfaces. The crown guards have a polished workmanship, as do the screw-down crown and chronograph pusher sleeves.

On the left side of the case, at the 10 o'clock position, there is a polished helium release valve. This valve is used to allow tiny helium molecules to escape from the inside of the case. These tiny helium molecules are so small that they can naturally pass through case and glass; They accumulate in the casing when diving using a diving bell. The helium release valve allows you to release them once you land.

BEZEL

The bezels of these two models are made of stainless steel and filled with a scratch-resistant, hardened ceramic inlay. Then, enamel numbers and signs were added around the bezel. There is a lume dot at the top of the bezel, at the starting point. This bezel is slightly improved compared to previous Seamaster models. It grips better, has a smoother action, and makes less rattling noise when turning.

Chronograph

The chronograph uses a column wheel design rather than a cam-driven design; This provides starting and stopping with a smoother movement. As we mentioned at the beginning of the review, it is operated via chronograph pushers located on both sides of the crown on the right side of the case.

In the blue model, the chronograph pushers are made of ceramic material and are in a blue tone to match the dial and bezel. Similarly, on the black model, the buttons are black for harmony. These buttons use screw-on “sleeves” to prevent water from entering the case.

The stopwatch feature can be started by pressing the button at the top. When pressed, the large central chronograph seconds hand on the dial begins to rotate. Press the button again to stop the chronograph, and press the bottom button to reset the chronograph.

Bracelet

The bracelet uses a multi-piece design; It consists of a large brushed center piece and exterior and interior pieces that use a combination of brushed and polished workmanship. The bracelet is solidly made and fastens with a push folding clasp. Additionally, the bracelet has a feature that allows micro-adjustments to the bracelet size with the press of a button.

Mechanism

The heart of the watch comes from the in-house produced Omega Master Chronometer caliber 9900, which oscillates at a rate of 25,200 vibrations per hour. Omega 9900 automatic movement contains 54 jewels and uses a magnetic-resistant silicon spring. Thanks to the series-mounted double barrel, this self-winding movement offers a generous 60-hour power reserve.

This beautifully crafted movement can be watched in action through the transparent sapphire case. The 9900 caliber uses Geneva waves with arabesque patterns as its crafting technique and, more importantly, it is a METAS certified Master Chronometer.

This means that the caliber must first be tested by the COSC and receive the COSC chronometer designation after achieving a minimum level of precision of only -4/+6 seconds deviation per day. Once calibrated, passed these tests, and received a COSC certificate, the caliber is sent to another laboratory called METAS.

METAS then tests the watch for a few other features; these include the advertised minimum waterproofing and magnetic resistance to electromagnetic fields up to 15,000 Gauss. It is then adjusted once again, but this time to reach a minimum precision of -0/+5 seconds per day; which is even more accurate than a prestigious COSC chronometer! Only then does the watch receive the title of Omega's Master Chronometer. Arguably one of the world's most difficult to surpass badges of excellence in mechanical watchmaking precision and accuracy.

Warranty

Omega recently started offering a generous 5-year warranty on all of its watches. PrestigeTime.com accepts this same warranty period on all new Omega watches. For more information about this watch or any other Omega model, contact one of our representatives.
