The Armitron MD17421 is a digital watch designed to provide a range of timekeeping and utility functions. Its core functionality revolves around displaying time, managing alarms, and offering stopwatch capabilities, all presented through an electro-luminescent display for readability in various conditions.
The primary function of the Armitron MD17421 is its Time Telling Mode. In this mode, the watch displays the current Hours, Minutes, Seconds, and the Day of the Week. It also supports both 12-hour and 24-hour (Military Time) formats, allowing users to choose their preferred display style. When the 12-hour format is selected, 'A' indicates a.m. times and 'P' indicates p.m. times, ensuring clarity.
Beyond basic time display, the watch incorporates a Calendar Mode. By pressing and holding the 'C' button from the Time Telling Mode, users can view the Month, Date, and Year. Releasing 'C' returns the watch to the Time Telling Mode. This feature is useful for quickly checking the full date without needing to adjust settings.
An essential utility of the MD17421 is its 24 Hour Alarm. This alarm can be set to a specific hour and minute. Once activated, the alarm symbol appears on the display, and the alarm will sound for 60 seconds at the preset time, or until any of the 'A', 'B', or 'C' buttons are pressed. This provides a reliable reminder function for daily tasks or appointments.
Complementing the alarm is the Hourly Chime. This feature, when activated, emits a single 'Beep' sound every full hour. It can be activated independently or in conjunction with the 24 Hour Alarm, offering a subtle auditory cue throughout the day. The watch allows for flexible activation: users can choose to have only the alarm, only the hourly chime, both, or neither.
For timing events, the watch includes a comprehensive Chronograph Mode. This mode measures Hours, Minutes, Seconds, and 1/100 of a second, making it suitable for tracking various activities. It also supports a Lap Operation function, allowing users to record split times during an ongoing event without stopping the main timer. This is particularly useful for sports or other activities where intermediate timings are required.
The MD17421 also features a Second Time Zone mode. This allows users to set and keep track of a different time, which is convenient for travelers or individuals who need to monitor time in another geographical location. The Second Time Zone clock operates independently, providing a quick reference for foreign times.
Finally, the watch is equipped with INSTALITE - Electro Luminescent Display. This backlight feature illuminates the watch face, ensuring readability in low-light conditions. Pressing the 'D' button in any mode activates the backlight, which remains lit for 3 seconds.
Operating the Armitron MD17421 involves a series of button presses, with each button ('A', 'B', 'C', 'D') serving multiple functions depending on the mode.
To set the time, users start in the Time Telling Mode and press and hold 'A'. This causes the seconds to flash, which can be zeroed out by pressing 'C'. Subsequent presses of 'B' cycle through Hours, Minutes, Year, Months, and Date, each of which can be adjusted by pressing 'C'. Holding 'C' will advance the digits rapidly. Once all settings are correct, pressing 'A' ends the sequence and returns to the Time Telling Mode.
From the Time Telling Mode, pressing and holding 'B' enters the Alarm Mode, where the Alarm Hour flashes. Pressing 'A' initiates the setting process. 'C' is used to adjust the Alarm Hours. Pressing 'B' then makes the Alarm Minutes flash, which are also adjusted with 'C'. Pressing 'A' again concludes the alarm setting.
In the Alarm Mode, pressing 'C' cycles through the activation options: Alarm On, Hourly Chime On, Both On, and Both Off. The alarm symbol on the display indicates when the alarm is active.
To access the Chronograph Mode, users press 'B' once from the Time Telling Mode. Pressing 'C' starts the timing, and pressing 'C' again stops it. To reset the stopwatch to zero, 'A' is pressed.
While the stopwatch is running, pressing 'D' measures and displays split times. After the event, pressing 'C' stops the timing, and 'A' reveals the final split time. Pressing 'A' again resets the stopwatch.
From the Time Telling Mode, pressing 'B' three times enters the Second Time Zone Mode. Pressing and holding 'A' makes the Hours flash, which are adjusted with 'C'. Pressing 'B' then makes the Minutes flash, also adjusted with 'C'. Pressing 'A' ends the sequence.
In the Time Telling Mode, a simple press of 'A' toggles between the 12-hour and 24-hour formats.
The 'D' button activates the electro-luminescent backlight in any mode, providing temporary illumination for 3 seconds.
The Armitron MD17421 is designed with some considerations for maintenance, primarily regarding its power source and water resistance.
The manual advises users to change the battery when the watch starts to slow down, the display darkens, or the backlight fails. It emphasizes the importance of noting the old battery's polarity before removal to ensure the new one is installed correctly. Users are instructed to replace the battery with the same kind or an equivalent. The watch contains precise electronic components, and opening it should ideally be done by a qualified watch technician. However, it is explicitly stated that returning the watch to the manufacturer for battery replacement is not necessary; instead, it is recommended to take the timepiece to a local jeweler.
The watch is described as "WATER RESISTANT." A crucial instruction is to not operate push buttons below the surface of the water. This is a common limitation for water-resistant watches and is vital to prevent water ingress. If water or condensation appears inside the watch, it should be checked immediately, as water can corrode the internal electronic parts.
For more extensive service needs, such as cleaning, lubrication, battery changing (if not done locally), or crystal replacement, Armitron provides a network of approved Service Centers. These centers use genuine Armitron parts to ensure quality and performance. Free estimates are available for services not covered under warranty. For warranty repairs, proof of purchase is required.
Users are explicitly instructed not to return the watch for service where it was purchased. Instead, they should contact Armitron for a list of approved service centers or visit their website. When mailing the watch for service, it should be carefully packed in a sturdy box (gift boxes are not recommended as they will not be returned). Insuring the watch and requesting a return receipt is advised due to possible loss. Users are also cautioned against including special watch bands or other personal valuables in their shipment.
