![]() ![]() This is important because it means that any issues with power reserve are a result of insufficient winding. Oris calibre 400 movement full#In fact, I fully wound the stand-alone movement and observed that it ran for 125 hours before coming to a stop so we know that the watch is capable of storing enough energy and operates with sufficient efficiency to deliver the full 5-day power reserve with a little left in the tank. When manually winding this watch it takes more than 100 turns of the crown to fully wind it up, where most watches would be fully wound with about 40 turns of the crown. Before addressing this I think it is important to note that it takes a lot to fully wind a double barrel (5-day power reserve) watch. This 7-day test brought to light one of the first complaints I have heard from individuals who have purchased this watch and that is that they don’t seem to get the full 5-day power reserve as advertised by Oris. Oris calibre 400 movement how to#Fig 4 – Arrow indicating how to let down the power ![]() Servicing these watches should be straight forward for any watchmaker. This watch requires both and is marked with an arrow indicating you must loosen the screw and another pointing to the button to release the spring tension. Most watches require you to either turn a screw or depress a button. Also, the double release for the winding stem (a feature exceedingly rare in watchmaking) is also well marked. The click is clearly labeled with an arrow. For example, with two barrels it can be more difficult than normal to figure out how to release the power stored by the mainsprings before servicing the watch. ![]() Anything that is out of the ordinary is clearly marked to aid the watchmaker in his service. The watch comes apart and goes together easily. Often brands don’t think about what will happen when the watch needs to be serviced, but in this case, it is apparent that the needs of the watchmaker were considered. Pick one up here while they last.From the watchmaker’s perspective, it even looks like they designed the caliber 400 with after-sales service in mind. The movement also has well above average magnetic resistance, and comes with a 10-year warranty. Most notably, the Caliber 400 is among only a small handful of movements with a 5-day power reserve, allowing for more time off the wrist without winding. While not their first in-house movement, the Caliber 400 is their first modern automatic, one with some great specs and a respectable price to match. For Oris, the launch of the new and impressive Caliber 400 is certainly such an occasion. Always the culmination of years of research and development, not to mention significant financial investment, new movements tend to mark pivotal shifts in a brand’s history. Launching an in-house movement is no small occasion for a watch brand, particularly independent and value-driven brands. Limited to just 1,000 pieces, this is a version of the ProPilot not to miss out on. Lastly is a unique disk date display, which furthers the instrument-style aesthetic. A natural fit for a pilot’s watch, it adds complexity and purpose. Next is the addition of a GMT complication. First, the outside is coated in a mean looking gun-metal PVD, upping the watch’s modern attitude. The 57th Reno Air Races Limited Edition takes the 41mm version to another level with three distinct elements. ![]() One of, if not the, most successful modern pilot designs, now with molded lume, it’s a bit of a sleeper in Oris’ collection.
