2021 Aquacy'1769 Hei Matau' [Limited Edition - 1769 Pieces] 300 metre dive watch with a Miyota (Citizen) 9015 (24 jewels) automatic movement which runs at 28,800 bph/8'ticks' per second. In 1959, Citizen Watches established a movement-making factory in the town of Miyota, Japan. Most watch brands do not make their own movements in house, but rather use standard watch movements manufactured by specialised companies like Miyota who are part of the Citizen group of companies. The 9015 movement, first introduced in 2009, is found in many new micro brand watches because it is easily obtainable, has a desirable hacking function, and is considered a workhorse movement. On this particular watch the vintage sunray orange/yellow dial under 12 o'clock displays the Aquacy water drop logo inspired by the Hei Matau, a Maori symbol in the shape of a highly stylised fish hook that represents strength, good luck and safe travel across water.Above 6 o'clock, 1769 in distressed font is from James Cook's 1769 map of New Zealand. There is a date window at 3 o'clock and the watch features nice bright Super-LumiNova on the hands, markers and bezel. The time/date is adjusted by an embossed screw-down crown. The sapphire crystal is pristine with no scratches or imperfections. The stainless steel case is fitted with a helium escape valve (see below) and the stainless steel screw down case back is double sealed to maintain water resistance. This is embossed with the'Hei Matau' logo of Aquacy and also the limited edition number of the watch, in this case it is 0058/1769. Fitted on an Aquacy stainless steel bracelet with folding clasp and safety (spare links also included), the watch itself is in perfect working order and keeps excellent time.
It is presented with its swing tag, authenticity card, soft cloth, and tools in the original padded hard plastic case. Also included inside is an Aquacy black rubber watch strap. Case width (9 o'clock to 3 o'clock): 41 mm (excluding crown). Case thickness: 11.65mm (including crystal). The 1769 series of automatic dive watches from Aquacy draw their inspiration from the Hei Matau of the Maori people in New Zealand dating back thousands of years and Capt.James Cook's first exploration of the country in 1769. Aquacy blends traditional watchmaking with function, quality and a bit of history to create something exquisite. When Captain James Cook - generally regarded as one of history's most ambitious explorers - came upon New Zealand in 1769, he met the Maori people and was inspired by their durability and strength. Captain Cook became so impressed with Maori people that he would return to New Zealand three times, often commenting on the resolve and dedication of the people who lived there. Inspired also by the adventurous spirit of Captain James Cook, the watch displays a reproduction of his original handwriting, taken from his map of New Zealand. Aquacy is a watch brand based in the United States founded by Darrell Spencer.
The mission of Aquacy is to bring affordable quality dive watches to the marketplace. Like the Hei Matau collection, upon which the Aquacy brand is built, Aquacy pledges that every watch will represent strength, good luck and safe travels. Upscale Time, in business since 2006, is located in Lynchburg, Virginia (as are Aquacy, Arcanet and Oceaneva). Helium escape valve - Unless you're a professional diver, chances are you won't ever have to use the helium escape valve.
Mostly, the feature is there for professional divers diving to depths greater than 250 feet for extended periods of time. At depths greater than 250 ft, the gasses in water become toxic. When divers go on expeditions at these depths, they have to travel down in a diving bell, which is highly saturated with helium and hydrogen to counteract the toxic air found at these depths.
This is where the helium escape valve comes in handy. Because helium atoms are extremely small, they easily slip inside a watch case. This becomes a problem when the diving bell makes its ascent to the surface.As the bell depressurises, so does the watch. The build-up of helium atoms inside of the watch case could damage the watch and the resulting pressure could pop the crystal off of the case. However, if a watch has a helium escape valve, it can be opened during decompression to expel helium safely out of the watch. When it's not in use, it should be kept closed to prevent water and dirt from entering the watch case. There are both manual and automatic helium escape valves. With the manual option, the watch will feature a separate screw-down crown that you open as you ascend to let gasses escape.
When the pressure outside the watch reaches levels that are significantly different from levels inside of the watch, a one-way, spring-loaded valve is activated, releasing the trapped helium atoms and lowering the pressure inside of the watch. With the automatic option, when the pressure outside the watch reaches a level significantly different from that inside of the watch, a one-way, spring-loaded valve is activated, releasing the trapped helium atoms and lowering the pressure inside of the watch.
