Retro-cool design, timeless styling and a distinctive case have defined the Datron Collection for over 50 years. Inspired by the Movado archives, this timepiece features a 41mm case of stainless steel housing a chevron textured green dial fitted with a day window, a date window, and Swiss Super-LumiNova® accents. They’ve added a modern touch with an exquisite Swiss made automatic movement. A fluid three row bracelet in matching stainless steel and effortless push-button deployment clasp complete this essential piece.Automatic watches do not contain batteries. They are charged by the movement of your wrist. If the watch is not worn it will stop running in about 38 hours. To get it started, turn the crown clockwise about 20-30 times until the second-hand starts moving. You will most likely need to reset the time and date.Green Super-Luminnova® Dial With Index41mm Stainless Steel CaseSapphire CrystalSwiss Automatic Movement5ATM water resistantStainless Steel Link BraceletMovado Style #: 3650178
