Watch Description
DEEPSTAR II, UNMISTAKABLY AN AQUASTAR
The Aquastar Deepstar II is an evolution of the Deepstar from 1963. It is what would have been the logical successor of the original. It retains the same case dimensions of the Original and relies on the same bezel patent. The unique and uncluttered mono sub counter dial, and the patented multiple dive decompression bezel table make the Deepstar an unmatched diver-oriented tool with an instantly recognizable design.
In order to adhere to the original design lines, the Deepstar II is time only 3 hand dive watch, where the minute counter sub dial of the original Deepstar has now become a seconds running indicator.
Like its predecessor from 2020, the new Deepstar II reflects a fully modern vision of the Aquastar brand, and its enigmatic, innovative founder who shaped a pivotal moment in mechanical watch history. This moment in timekeeping history represented a conscious shift from wrist watches as time-telling devices, to purpose-built tools designed for very specific fields, like diving and exploration. Aquastar didn’t invent the dive watch, but the brand crystallized its purpose in a singular vision, influencing an entire industry with category-defining innovations.

# Aquastar Deepstar II Review by A.I. WatchMetrics
## Watch Summary
The Aquastar Deepstar II is a vintage-inspired compressor-style dive watch in a wearable 39mm stainless steel case, featuring a patented unidirectional rotating bezel with 12 sapphire balls that evoke the original 1960s model's pressure-activated design, a sunray dial with applied luminous indices and date at 6 o'clock, screw-down knurled crown offset at 4 o'clock, and helium escape valve, powered by a reliable COSC-certified Sellita SW200-1 automatic movement offering 38 hours of power reserve, making it perfect for enthusiasts with smaller wrists seeking a 500m tool watch blending heritage aesthetics with contemporary robustness.
## Overall Watch Rating: 6.9/10.0
**Material Metric (9.2/10.0)** - Premium 316L stainless steel paired with double-domed AR-coated sapphire and meticulous brushed/polished finishing benchmarks against high-end divers like the Omega Seamaster 300.
**Dials & Design Metric (8.8/10.0)** - The compelling sunray dial, applied markers, and innovative sapphire-ball bezel deliver standout vintage compressor charm comparable to the Bulova Oceanographer Devil Diver.
**History & Innovation Metric (8.2/10.0)** - Rich legacy as a 1960s compressor pioneer revived with modern patented bezel tech earns scores akin to revived icons like the Squale 1521.
**Versatility Metric (8.2/10.0)** - Excellent as a daily sports diver with rubber strap compatibility and compact sizing matches the adaptability of the Tudor Black Bay Fifty-Eight.
**Brand Metric (7.0/10.0)** - Niche Swiss revival with enthusiast appeal and low production places it alongside micro-premium brands like Halios or Nivada Grenchen.
**Rarity Metric (6.5/10.0)** - At $3,400 retail with boutique production volumes, it offers moderate exclusivity similar to limited-run divers from Doxa.
**Movement Metric (5.7/10.0)** - Dependable COSC Sellita SW200-1 provides solid accuracy but lacks in-house flair, scoring like standard automatics in Certina or Mido divers.
**Functions Metric (4.7/10.0)** - Basic time-and-date functionality with strong lume falls short of multifunction peers like the Zodiac Super Sea Wolf.
**Complications Metric (3.9/10.0)** - Simple date window at 6 o'clock is reliable but basic, on par with entry-level divers from Steinhart.
## Total Performance Score (TPS): 4.0
## WM Collector Grade: C
## Performance Insights: Excels in materials, design, and heritage but dragged by standard movement and limited functions; TPS of 4.0 indicates average value versus an implied price of $5200.
## TPS Interpretation: Fair Value: The watch provides robust construction and nostalgic appeal suitable for its price, though enhanced complications would elevate it further.
