Omega Seamaster Aqua Terra 150M
Omega has wowed us yet again with this new release – the Seamaster Aqua Terra 150M. This model carries the traditional Seamaster aesthetic with its clean, angular lines and robust finish but is fit for use both in the water and on dry land. The main difference between the Aqua Terra and other watches form the Seamaster collection is the inclusion of a GMT function, which allows the wearer to read a second time zone whilst observing home time.
The Aqua Terra comes in stainless steel, solid 18kt red gold, and a bi-metal option (stainless steel and red gold). These models can be outfitted with your choice of either a stainless steel bracelet or a leather strap. The straps come in varying color options depending on the case material: black for the stainless steel and bi-metal option, or brown for the solid 18kt gold edition. The stainless steel bracelet carries a folding clasp, while the leather straps offer a tang type buckle, crafted to complement the case material.
The case on this trendy timepiece carries a case diameter of 43mm, which is just below over sized. The main crown is screw locked enabling the 150 meters water resistance on this piece. The fixed bezel holds the dial window which is crafted from sapphire. Sapphire crystal is used because of its extreme scratch resistant properties. Also in sapphire crystal is the case back which reveals the decorated and precise Omega Co-Axial movement Caliber 8605/8615 self-winding mechanical.
Co-Axial movements are now almost the standard from Omega, which hails it as the most precise self-winding available. Co-Axial movements differ to regular movements mainly through the escapement. Regular movements use a lever escapement but the Co-Axial movements transfer the energy via a balance roller which carries a pallet and an impulse pin and an anchor and three pallets. Though many might not understand the complex engineering used to bring this innovation to life, the result is a movement with less friction and greater transfer of energy. This enables the piece to be more precise over time. All watches fitted with the Co-Axial movement are backed by a 4 year warranty plan.
As far as precision goes, the Seamaster Aqua Terra models are awarded the chronometer certification from the COSC. Chronometers exhibit an accuracy of -4/+6 seconds per day, in 5 positions, over 15 days, to gain the certification. Certification by the COSC is a rarity in Swiss watchmaking with only 5% of watches leaving Switzerland having this title.
The dial features striations which Omega says is reminiscent of the wooden floor boards on a boat. The hour markers used are rhodium colored indexes with lume for nighttime readability. The hands also carry lume on this model. The internal, central subdial is the GMT counter. The second time zone is indicated by a central arrow head hand tipped in red. The dial also features a conservative minute track using white demarcations on the flange. At the 6 position on the Omega Seamaster Aqua Terra 150M is a vaulted date aperture.
