Quick TakeThis isn't just another green watch; the Marinemaster M-40 Woodpecker Green is a shot of adrenaline for the wrist. That dial! The vibrant green combined with the Fortis O-pattern texture gives it an almost electric feel, like staring into a canopy after a tropical downpour. But don't let the lively color fool you; this thing is built tough. We're talking recycled stainless steel shaped into a perfectly wearable 40mm case, ready to shrug off bumps and scrapes. And with 300 meters of water resistance thanks to that triple-gasket screw-down crown and Performance FKM seals, it’s practically begging you to take it swimming, diving, or just get caught in a monsoon. The Gear Bezel isn't just for show either; it's got that satisfying mechanical click you want in a tool watch. Inside, the reliable UW-30 automatic keeps things ticking precisely, chronometer-certified no less, with a handy date function. And when the lights go down, that blue-glowing Superluminova X1 bursts into life on the hands and markers. Strapped onto the comfy, practically indestructible FKM rubber Horizon strap, this Fortis is pure, unadulterated fun blended with serious capability.

DescriptionThe Fortis Marinemaster M-40, designated by reference number F8120007, presents a robust architecture centered around a 40 millimeter diameter case constructed from recycled stainless steel. This material choice reflects a contemporary approach to resource utilization while maintaining the necessary structural integrity for demanding applications. The case geometry includes a lug-to-lug distance measuring 43 millimeters and an overall height profile of 12 millimeters, contributing to its wrist presence and wearability characteristics. Ensuring protection against water ingress, the watch is rated for a depth of 300 meters, equivalent to 30 atmospheres or 1000 feet. This significant water resistance is achieved through meticulous engineering, incorporating a screw-down crown equipped with a triple gasket system and specialized Performance FKM gaskets utilized throughout the case assembly. These fluoroelastomer gaskets provide superior sealing properties and resistance to environmental factors. The case back is fashioned from solid stainless steel and features an intricate ultra-engraving, adding a distinctive design element while sealing the movement. Positioned atop the case is a unidirectional Gear Bezel, a functional component designed for precise timing intervals, characteristic of dive-oriented timepieces. The watch head itself possesses a mass of 76 grams, excluding the strap. Protecting the dial is a sapphire crystal, renowned for its exceptional scratch resistance, further enhanced with an anti-reflective coating applied to both its inner and outer surfaces to maximize legibility under various lighting conditions by minimizing glare.

Powering the Marinemaster M-40 is the Automatic Performance Calibre UW-30, a self-winding mechanical movement engineered for reliability and precision. This calibre operates as a chronometer, indicating adherence to stringent timekeeping standards. Functionally, it provides central hours, minutes, and sweep seconds indication, alongside a date complication displayed through an aperture on the dial. The movement offers a power reserve of approximately 38 hours when fully wound. The visual interface, the dial, is presented in a vibrant Woodpecker Green colorway, featuring the distinctive Fortis O-pattern texture across its surface. Legibility in low-light conditions is paramount, addressed through the application of Superluminova X1 luminous material on the applied hour markers; this specific compound emits a blue glow. The primary time-telling hands, indicating hours and minutes, are metallic and generously filled with the same Superluminova X1 material. The sweep second hand is also metallic and incorporates a Superluminova X1 Bull's Eye element near its tip for enhanced visibility of its motion. The watch is secured to the wrist via the Horizon Strap, fabricated from hypoallergenic FKM rubber. This strap material is selected for its notable resistance properties against heat, various chemicals, and ultraviolet radiation, rendering it suitable for diverse environments including aquatic activities. It attaches using a robust screw pin system for secure mounting to the lugs and fastens with a conventional stainless steel pin buckle system, ensuring ease of use and dependable closure during wear.
