# Hamilton Boulton Small Second Review by A.I. WatchMetrics

## Watch Summary
The Hamilton Boulton Small Second is a vintage-inspired dress watch with a distinctive Art Deco rectangular cushion case in stainless steel, featuring an elegant opaline silver dial accented by applied indices, blued hands, and a small seconds subdial at 6 o'clock, powered by the manual-wind Caliber H-50 movement with an impressive 80-hour power reserve, perfect for the style-conscious professional seeking timeless formal elegance without ostentation.

## Overall Watch Rating: 6.0/10.0

**Material Metric (9.2/10.0)** - Premium stainless steel case with double-domed sapphire crystal and meticulous brushed/polished finishing punches above its weight, comparable to entry-level luxury like Oris.
**Dials & Design Metric (8.7/10.0)** - The iconic Boulton rectangular shape and refined opaline dial with guilloche center deliver standout vintage charm akin to early 20th-century dress icons.
**Movement Metric (8.4/10.0)** - The H-50 manual caliber offers exceptional 80-hour power reserve and reliable ETA-based performance, on par with upgraded workhorses in Tudor classics.
**History & Innovation Metric (7.3/10.0)** - Hamilton's storied railroad and military heritage elevates it to established status, though innovation relies on refined Swiss mechanical traditions.
**Versatility Metric (6.8/10.0)** - Suited primarily for formal wear with its slim profile and leather strap, it dips into casual vintage territory but limited by 30m water resistance.
**Brand Metric (5.5/10.0)** - Hamilton provides dependable mid-tier Swiss quality with global recognition, benchmarking against reliable peers like Seiko Prospex.
**Rarity Metric (4.1/10.0)** - At under $1,000 retail with broad production, it offers accessible appeal without the scarcity of limited editions.
**Complications Metric (3.9/10.0)** - The small seconds subdial adds subtle sophistication but remains basic compared to multifunction pieces from Omega.
**Functions Metric (0.2/10.0)** - Limited to hours, minutes, and small seconds, it underdelivers on utility versus multifunction tool watches like the Citizen Eco-Drive.

## Total Performance Score (TPS): 5.2

## WM Collector Grade: A+

## Performance Insights: Excels in materials, design, and movement for superior build quality, tempered by minimal functions and average rarity; exceptional value trading at $945 versus a $7,500 implied price.

## TPS Interpretation: Exceptional Value: The watch vastly overdelivers on craftsmanship and heritage relative to its modest price, making it a steal for vintage dress enthusiasts.
