"Oris Aquis Pro Date 01 400 7777 7155-Set. Finished in a full black plated Titanium case and blue rubber strap with a matching Titanium security folding clasp with extension. The Aquis Pro features a 49.50mm case. The Sapphire Crystal glass is domed on both sides and has anti-reflective coating inside. The AquisPro is rated 4000m Water resistant. Featuring a raft of innovations and functions, the 01 400 7777 7155-Set is a serious piece of kit and features a Rotation Safety System or RSS which is activated by holding the bezels black vulcanized rubber edge and lifting it. This also releases the bezels black ceramic minutes scale top ring. When activated, a stainless steel ring appears around the edge of the top ring. To set the timer, with the stainless steel ring now visible, turn the top ring anti-clockwise and align the number on it that corresponds to your allocated dive time with the watch's minutes hand. To secure the time, once in place, push the top ring down until it clicks into position. The timer scale is now secure and you are ready to begin your dive. Calibre 400 is an entirely new movement, independently conceived by Oris, and sets the new standard for automatic mechanical movements. It has a five-day power reserve (120 hours), is highly resistant to magnetism, and comes with 10-year recommended service intervals and a 10-year warranty. When conceptualising Calibre 400, Oris’s engineers recognised that these days we may not wear the same watch every day. If you put a standard mechanical watch down for a day or two, it will stop as the power reserve runs down. Calibre 400 has a five-day power reserve, so it’ll still be running if you’ve not worn your watch between, say, Thursday and Tuesday. It delivers this longer period of use via twin barrels, both of which house an extended mainspring, each long enough to store two-and-a-half days of power. What we like: Pro by name and Pro by nature. The AquisPro is rated to 1000m water resistant. A solid watch to wear and enjoy. The Titanium makes this a very light watch to wear."
