The Smith and Wesson 357 Aviator Tritium watch is a good value for those looking for a Tritium watch for night time use. Some have commented on the brightness of the watch, or more so, on the lack thereof. Two things must be noted here. First, this watch is advertised as being a 43mm case watch and this is true. However, the actual face is more like 37mm so the appearance of the watch face is much smaller. Second, this watch uses T-25 Tritium tubes which are not by any means as bright as T-100 Tritium tubes. These numbers represent the amount of "gas" that is inside of the Tritium vials. T-100 vials hold four times as much volume as does the T-25 vials. Therefore, T-25 tubes will be only one fourth as bright as the T-100 tubes. You want brighter tubes, you must by a more exspensive watch... Simple, huh? I own several other Tritium tube watches including Luminox and Deep Blue and they all "glow" exactly the same with the exception of a Deep Blue with T-100 tubes. As far as the time piece goes, I have had no problems with the SW 357 Tritium I purchased. Well made case and bracelet and I have had the watch to 110 feet with no leaks. By the way, this case is used by several other manufacturers such as Traser, Humvee, and others with a number of different configurations including saphire crystals and depths advertised to 500 meters. Why a four star rating you ask? The watch face could and should be a bit larger!
