Omega Seamaster Diver 300M Co-Axial 42mm Limited Edition Review

Amongst Omega's fine line of Seamasters, the 42mm limited edition in 18K Sedna has amassed a large following of its own. Omegas are always a customer favorite, but we're especially excited about this magnificent timepiece.

This Omega Seamaster Diver 300mm stands out in several ways. Like all Seamasters, from a certain perspective, the piece is certainly recognizable as an Omega Seamaster. However, like every new edition, this limited edition Seamaster has several innovative features that make it it's own unique form of artwork.

Omega has mastered asymmetry and a delicate balance in following the same overlapping aesthetics that Seamasters are known for while creating masterful distinctive details that set each variation apart. Each Semester is a profoundly eloquent watch. This edition shares the fundamental perspectives of a Seamaster Diver 300, and each holds an atmosphere of ambition all its own. This limited edition is a fast favorite because it offers a great deal of geometrical features in combinations not found anywhere else in the Seamaster Diver family.

Omega seems to make their most stand-apart pieces limited editions; and by only crafting 2,500 pieces this watch is truly limited and unfortunately will become harder and harder to obtain the longer you wait.

For the Seamaster Diver 300 M Co-Axial Master Chronometer 42mm Limited Edition, Omega has used grade-2 titanium, on this watch's case which merges nicely with its provided bracelet. This combination was used for its unique earth-tone shades that smoothly offset the 18K Sedna™ gold Crown and bezel. The designer found a pleasant and realistic combination by converging tantalum into the base of the bezel, almost creating a metallic shine with a faintly blue chatoyancy from at least 3-points of perspective. The camera tends to only capture a metallic blue-grey but like all Omega watches, this exquisite timepiece is much more magnificent in person.

The limited-edition Seamaster Diver 300mm stays true to much of the desirable aesthetics found in other Omega favorites. It is similar in ways like how the titanium dial features the familiar ocean waves with the unique quality being the waves on this watch, are brushed-polished and appear to be in raised-relief form. The indexes are raised as well and inlaid with Omega's white Super-LumaNova as are the hands. This creates a texture and feel pouring over with fine artisanship and radiating an ode to quality from several points of perspective. Basically the watch is beautiful to the admirer as it is to the wearer. can help find custom bracelets based on each customer's preference. We have several exciting options and combinations to choose from. The manufacturers at Omega went with a linked bracelet that perfectly matches the 42mm case. The steel on gold links of the bracelet seems to create a perpetual flow from case to the bracelet to the case again. A lot of our customers like to have several options in bracelets and we have a selection and tools available to help quickly switch bands to match whatever you might decide to wear, for any occasion. However, there's no doubt that the Craftsmen at Omega went all out rendering such a perfect combination between watch and bracelet in this limited edition Seamaster.

The dynamic textures and tones of the face are clearly visible through a sapphire crystal lens. Like all of the newer Omega Seamaster, the COSC certified Master Chronometer clockworks are water resistant within the case. Omega boasts that the water-resistance of this watch is capable of withstanding depths up to 300 meters. This high level of resistance is in part due to Omega's patented screw-in self-locking crown.

This is one more example of Omega's finest. All our Seamasters can be appreciated through their appearance alone, but each are also verified and functional to the highest standards set by Sweden's COSC. Each edition is unique in almost a spiritual way that seems to reflect the feelings and inspirations of the artist who designed each piece. There is a Seamaster for everyone, each with all of the functionality and durability one expects from any of the luxury watches available from Exquisitetimepieces.Com.

We carry some of the world's finest timepieces, and through our online options, we make these watches easily available to our busiest customers. However the Seamaster Diver 300M with Co-Axial Master Chronometer in 42mm is a limited edition, and there has only been 2500 made. So no matter what efforts we take to make this luxurious watch available to you, once it's gone--it's gone. If this is the Seamaster that has been created for you, act fast and contact us today--while it is still available.
