Watch Description
https://www.analogshift.com/products/omega-seamaster-300-big-triangle
Omega adapted the Seamaster of the 1940s, adapting a technology from submarines—rubber O-rings—to seal the back of the case.
Sure that this was a winning design, Omega submitted this new Seamaster to the Laboratory for Water Resistance in Geneva, where it was subjected to the same conditions it would see during a dive: punishing pressure, the same as at 60 meters, and rapid changes of temperature. It passed, and the Seamaster was rechristened the Seamaster 300 and launched in 1957. As Omega’s answer to its longtime rival Rolex’s Submariner, the Seamaster found its depth.
But it did not stagnate—as underwater breathing technology continued to improve, Omega tweaked the design of the Seamaster throughout the remainder of the 1950s and on to the 1960s, and hit on a legend.
This watch, the Reference 166.024, is like its cousin, the Reference 165.024, but with an additional date window. Like the Speedmaster Reference 145.012, the case of the Seamaster 166.024 was made by Huguenin Frères, and is notable for its distinctive asymmetrical shape. The dial is also of note, due to its unusual configuration: a large triangle at 12 o’clock which has given rise to the nickname “Big Triangle.”

# Omega Seamaster 300 Big Triangle Date Review by A.I. WatchMetrics
## Watch Summary
The Omega Seamaster 300 Big Triangle Date is a vintage-inspired sports dive watch that faithfully recreates the iconic 1950s CK2913 reference with its 41mm stainless steel case, black dial featuring oversized triangular lume pip at 12 o'clock, sword-style hands, and a bi-directional aluminum dive bezel, targeting serious collectors and adventure enthusiasts who value historical accuracy blended with modern reliability; its standout features include the METAS-certified anti-magnetic performance and robust 300m water resistance, powered by the automatic Co-Axial Master Chronometer Calibre 8912 offering a 60-hour power reserve.
## Overall Watch Rating: 8.0/10.0
**History & Innovation Metric (9.5/10.0)** - Omega's pioneering role in dive watch history with the original Seamaster 300 and innovations like Co-Axial escapement rival the legacies of Blancpain's Fifty Fathoms.
**Dials & Design Metric (9.4/10.0)** - The faithful recreation of the Big Triangle vintage aesthetic with superb legibility and balanced proportions stands out even among modern reissues like the Rolex Opalin.
**Movement Metric (9.2/10.0)** - The Calibre 8912 delivers exceptional accuracy and anti-magnetism beyond standard chronometers, comparable to top ETA-based upgrades in Grand Seiko.
**Cohesiveness Metric (9.2/10.0)** - Every element from bezel to indices harmonizes perfectly in this single-watch review, evoking unified vintage dive coherence like a well-curated microbrand lineup.
**Brand Metric (8.8/10.0)** - Omega's luxury status with deep heritage in professional tool watches matches peers like Rolex in global recognition.
**Versatility Metric (8.9/10.0)** - This diver transitions seamlessly from underwater adventures to casual wear thanks to its rubber strap and balanced sizing, outperforming chunkier modern divers.
**Material Metric (8.7/10.0)** - Premium 316L steel construction with sapphire crystal and detailed brushing holds up well against similar spec Tudors.
**Rarity Metric (6.9/10.0)** - At its mid-luxury price point, it offers solid exclusivity without the scarcity of limited-edition Patek dive models.
**Functions Metric (6.5/10.0)** - Basic time and date with strong lume and dive capabilities provide reliable utility akin to entry-level Seiko Prospex.
**Complications Metric (3.9/10.0)** - The simple date window delivers essential functionality but lacks the complexity found in chronograph-laden Omegas.
## Total Performance Score (TPS): 5.2
## WM Collector Grade: B
## Performance Insights: Exceptional design, history, and movement shine brightly, while basic complications and functions temper value against the premium price, offering solid but not standout performance versus an implied $9,200 fair value.
## TPS Interpretation: Average Value: The watch matches expected performance for its segment with strong heritage offsetting modest functionality.
