# Vertex MP45 Monopusher Heritage Edition Review by A.I. WatchMetrics


## Watch Summary
The Vertex MP45 Monopusher Heritage Edition is a vintage military-inspired chronograph blending tool-watch ruggedness with collector appeal, featuring an asymmetric black sunburst dial, tan indices, and a distinctive monopusher layout originally designed for British forces in 1945, powered by a manual-wind Sellita SW510 C01 movement with 60 hours of power reserve.

## Overall Watch Rating: 8.4/10.0

**Dials & Design Metric (9.5/10.0)** - The iconic monopusher layout and vintage proportions deliver exceptional legibility and historical charm, surpassing many modern homages like the Zelos Swordfish.
**Movement Metric (9.5/10.0)** - The Sellita SW510 C01 monopusher chronograph offers high complexity and reliable performance with 60-hour reserve, on par with ETA 7750-based customs in microbrands.
**Complications Metric (9.2/10.0)** - The integrated monopusher chronograph with 45-minute counter provides smooth, efficient operation comparable to higher-end Sellita Valjoux modules.
**Material Metric (9.2/10.0)** - Premium 316L stainless steel case with double-domed AR-coated sapphire excels in finishing and durability, matching Oris or Christopher Ward tool watches.
**Rarity Metric (7.0/10.0)** - Limited to 150 pieces at around $4,500, it offers solid exclusivity similar to other microbrand heritage reissues but not ultra-rare like 50-piece LEs.
**History & Innovation Metric (8.0/10.0)** - Rooted in WWII military monopusher legacy with faithful recreation, it stands alongside revived icons like the Sangreal Glorious but lacks groundbreaking new tech.
**Functions Metric (8.8/10.0)** - Core timekeeping plus monopusher chrono delivers robust utility, exceeding basic three-handers like the Seiko 5 Sports.
**Versatility Metric (8.2/10.0)** - Balances heritage sport with casual dress-up potential across occasions, akin to a Hamilton Khaki Chrono but elevated by vintage styling.
**Brand Metric (6.5/10.0)** - Vertex's revived British heritage garners enthusiast respect like Bremont's entry models, though it trails mainstream premiums like Tudor.

## Total Performance Score (TPS): 4.5
## TPS Interpretation: Modest Value: The watch delivers strong heritage complications and design but at a price where more established brands offer similar specs.

## WM Collector Grade: B-
## Performance Insights: Excels in movement, complications, and aesthetics for a compelling heritage piece that punches above its weight against mid-tier luxury chronographs, though brand prestige tempers overall value.
