Quick TakeThis Aquamarine variant of the SUB 300 Beta isn't just another dive watch; it's a bold statement wrapped around your wrist, a conversation starter that screams adventure with a surprisingly sophisticated accent. Imagine it: the sun glinting off that captivating sunray dial with its subtle wave pattern, a constant reminder of the deep blue it's engineered to conquer. The 42.5mm case sits just right, substantial enough to feel like a serious piece of kit but slim enough at 11.95mm to slide under a cuff when you're back on dry land, perhaps recounting tales of your latest underwater exploit. That black ceramic bezel isn't just for show; it's a tactile link to the watch's purposeful design, rotating with a satisfying precision that speaks to its no-nonsense dive functionality. And whether you opt for the cool embrace of the "Beads of Rice" bracelet or the rugged flexibility of the FKM rubber, that ratcheting clasp is pure genius – a small detail that makes a world of difference when you're gearing up. It’s a watch that effortlessly bridges two worlds: the demanding realm of underwater exploration and the style-conscious urban landscape.
DescriptionThe timepiece in question, designated SUB 300 Beta Aquamarine with stock keeping unit 830.10.241.10, incorporates a Swiss-manufactured self-winding mechanical movement. This calibre operates at a frequency of 28,800 vibrations per hour, which translates to 4.0 Hertz, ensuring precise timekeeping. The movement, which is decorated by DOXA, provides a power reserve of approximately 38 hours. Indications displayed include hours, minutes, seconds, and the date. The watch's architecture is centered around a stainless steel case, possessing a diameter of 42.50 millimeters and a lug-to-lug dimension of 44.50 millimeters. Its vertical profile, or height, measures a relatively slender 11.95 millimeters, contributing to its wearability. Security against water ingress is robust, with a rating of 30 atmospheres, equivalent to 300 meters or 984 feet. This is further reinforced by a screw-down crown and a stainless steel screw-down case back.
Protecting the dial is a scratch-resistant sapphire crystal. A significant operational feature is the unidirectional rotating bezel, fabricated from ceramic and calibrated in meters, essential for dive time tracking. Furthermore, the inclusion of a helium release valve underscores its professional diving capabilities, allowing for the safe emission of helium gas during saturation diving decompression. The dial itself presents a sunray finish, enhanced with a stamped wave structure, providing a textured and visually dynamic background for the time indicators. Strap options cater to diverse preferences, offering either a stainless steel "Beads of Rice" bracelet or a black FKM rubber strap. Both selections are equipped with a folding clasp that integrates a ratcheting wetsuit extension, allowing for quick adjustments over a dive suit. The lug width for strap attachment is standardized at 20.00 millimeters. This redesigned iteration maintains core tool watch attributes while presenting a refined aesthetic suitable for various environments.
