If your watch has a date in a different location, say a tilted date at 4:00, then it means the watch manufacturer used an NH35A with a 3:00 date position and cutout the date window at the 4:00 position.Īlso keep in mind that although unlikely, it is possible the watch manufacturer printed a custom datewheel – again, possible but unlikely. To determine which date position your raw movement has, point the crown to the right and look for the number that reads from left to right – is it at 3:00 or 6:00? The location will determine the way the dates are printed on the datewheel. The 3:00 date version is the most common. The variations include the location where the movement was produced, date position, calendar color, and hand fitting type.įrom the factory, the NH35A has the date at 3:00 or 6:00. This information is mostly useful for watch manufacturers, but can also be useful if you intend on swapping your movement for any reason. While all are considered to be “NH35A”, there can be different reference numbers based on each combination of variable options. The NH35A has several variations depending on a few variables.

Crown Position Functions:Ġ (against the case): Clockwise = Manual Winding / Counterclockwise = Nothingġ (pulled out one click): Clockwise = nothing / Counterclockwise = Date settingĢ (pulled out two clicks): Time setting clockwise and counterclockwise Reference Variations: This movement is also equipped with the Seiko Magic Lever, so shaking the watch side to side should get it going almost immediately. So what does fully wound up mean? The NH35A should be fully wound after about 55 manual turns of the crown. TMI states that measurements should be done within 10-60 minutes after the movement is fully wound up.

Note: When you attempt to get a measurement of your watch’s accuracy, it’s important to make sure your watch is fully wound or the lack of power reserve may skew the test results. This shouldn’t have any noticeable bearing on the accuracy, but it’s interesting nonetheless. They recorded these accuracy measurements without the date complication being active. In the technical documentation, Time Module claims that the NH35A accuracy range is within -20~+40 seconds per day under normal conditions. for example, the NH36 is an unbranded version of the 4R36 (day + date) found in the Next Generation Orange Monster. It’s also important to note that the Seiko NH35A movement is basically an unbranded version of the Seiko caliber 4R35. Some of the topics covered in the caliber listing: They also have NE calibers that are labeled as “Premium” Mechanical Series. Time Module aka Seiko Instruments labels the NH calibers as part of the “Basic Mechanical Movement” Series.

The NH35A is currently one of the world’s most popular automatic movements and is widely available in many affordable/ microbrand watches. The earliest documentation on this movement that we were able to find was issued on, this also corresponds with the 2011-2012 time frame that the first NH35A powered watches started hitting the market.
