The Omega Seamaster Aqua Terra 150M is one of the most celebrated collections in modern Swiss watchmaking, born from Omega's storied maritime heritage and refined over decades into a watch that transitions effortlessly from the boardroom to the waterfront. The Aqua Terra line introduced the now-iconic "teak" horizontal dial motif — evoking the wood decking of a luxury yacht — and has since expanded into precious-metal and gem-set configurations that position it firmly in the luxury dress-sport category. Reference 220.58.38.20.99.005 represents the pinnacle of that evolution, crafted for a discerning collector who demands both technical excellence and jewellery-grade beauty.

The 38mm case of ref. 220.58.38.20.99.005 is rendered entirely in Sedna Gold, Omega's proprietary 18-carat red-gold alloy developed to resist the fading that can affect traditional rose gold over time. Sedna Gold's warm, rich hue provides a flattering backdrop for the diamond-set bezel, where individually selected stones encircle the dial in a continuous pavé-style setting that elevates this Aqua Terra well beyond conventional sport-watch territory. The case dimensions — 38mm — strike the ideal balance for a ladies' or smaller-wristed wearer who values presence without bulk.

The dial of this Omega Seamaster Aqua Terra is set with white sapphire indexes that catch and scatter ambient light with an intensity that diamonds cannot replicate, creating an ever-changing spectacle on the wrist. The overall composition — Sedna Gold case, diamond bezel, and gem-set white sapphire hour markers — is a study in tonal harmony, warm gold and cool white playing off each other against what is described as a white dial ground. Every element is finished to Omega's exacting manufacture standards, from the polished facets of the case to the hand-applied indexes.

At the heart of this timepiece beats Omega's Co-Axial Master Chronometer movement, the brand's highest-grade caliber family and the only movement in the world certified by METAS — the Swiss Federal Institute of Metrology — to meet Master Chronometer standards. This certification guarantees superior precision, resistance to magnetic fields of up to 15,000 gauss, and chronometric performance verified across multiple tests. Powering such an opulent case with Omega's most rigorous movement is a statement of intent: this is not merely a beautiful object but a serious instrument.

The watch is presented on a supple alligator leather strap that completes the high-jewellery sensibility of the piece, offering comfort and elegance in equal measure. Alligator leather is the traditional choice of the finest Swiss maisons for their precious-metal references, and its natural texture complements Sedna Gold beautifully. Bizak & Co. is pleased to offer this reference brand new, complete with manufacturer box and papers, ensuring full warranty coverage and complete provenance for your investment.

Buying the Omega Seamaster Aqua Terra 150M ref. 220.58.38.20.99.005 from Bizak & Co. means acquiring a timepiece that is simultaneously a feat of Swiss engineering, a wearable work of jewellery art, and a collectible reference in one of the world's most iconic watch families. Our team of luxury watch specialists is available to answer every question and guide you through your purchase with the confidence and service you deserve. Reach out today to secure this exceptional Omega at the best price.

FAQ

1. What makes the Omega Seamaster Aqua Terra 220.58.38.20.99.005 special?
Reference 220.58.38.20.99.005 combines Omega's exclusive Sedna Gold case material with a diamond-set bezel and white sapphire index dial, elevating the Aqua Terra into high-jewellery territory. It is also certified as a Master Chronometer, meaning it meets the Swiss Federal Institute of Metrology's strictest standards for precision and magnetic resistance. This dual identity — precious-metal artistry and elite movement certification — makes it highly distinctive.

2. What movement powers the Omega Seamaster Aqua Terra 150M ref. 220.58.38.20.99.005?
This Aqua Terra is powered by Omega's Co-Axial Master Chronometer movement, the brand's most advanced caliber family certified by METAS to resist magnetic fields of up to 15,000 gauss. The Co-Axial escapement reduces friction and wear compared to a traditional lever escapement, contributing to long-term accuracy and lower service frequency. The Master Chronometer designation is the highest movement certification Omega offers.

3. What is the case size of this Omega Aqua Terra ladies' watch?
The case measures 38mm in diameter, a size Omega positions within its ladies' Seamaster Aqua Terra lineup while remaining versatile enough for any wrist that prefers a refined, medium-scale profile. The case is crafted entirely in Sedna Gold, Omega's proprietary 18-carat rose-gold alloy engineered for lasting color stability. At 38mm it offers meaningful wrist presence without overwhelming a smaller wrist.

4. Is the Omega Seamaster Aqua Terra 150M suitable for everyday wear?
The Aqua Terra 150M is engineered to withstand 150 metres of water resistance, making it genuinely capable in aquatic environments while being refined enough for formal occasions. The alligator leather strap on this reference orientates it toward dressy daily wear rather than intensive water activities, as leather straps are best kept dry. For a collector who rotates between smart and sophisticated settings, this watch is an ideal everyday choice.

5. What is the dial and bezel made of on reference 220.58.38.20.99.005?
The bezel is set with diamonds in a Sedna Gold frame, providing a continuous ring of sparkle that defines the watch's jewellery character. The dial features white sapphire indexes — precious gemstones selected for their exceptional hardness and brilliant light performance — set against a white dial ground. Together, bezel and dial create a cohesive gem-set aesthetic unique to this precious-metal Aqua Terra configuration.

6. How can I buy the Omega Aqua Terra 220.58.38.20.99.005 and is it a good investment?
