Deep Blue Watches has announced a flash sale for the April Fools' Day weekend, featuring significant discounts on two specific dive watch collections. The promotion highlights the Aqua Diver Auto GMT for $129 and the Ocean Master 500 for $179. These deals are explicitly marketed as short-term offers available only for the duration of the weekend and are shipping directly from the company's New York headquarters. The Aqua Diver Auto GMT is available with either a blue or black dial and features a 40mm case that is 13mm thick. It is powered by a Seiko NH34 GMT automatic 24-jewel movement with a date function and includes a 120-click unidirectional sapphire bezel. The watch is built with a sapphire crystal with anti-reflective coating, Superluminova for low-light visibility, and a screw-down crown and caseback for water resistance. The Ocean Master 500 is also featured in the sale, equipped with a Swiss Automatic Sellita SW200 movement. This model utilizes a 40mm case and is available in four different styles, all of which come mounted on an FKM natural rubber strap. While the sale focus is on these two models, the brand encourages enthusiasts to visit their website for additional watch options and ongoing deals.
