The SKMEI 2101 is an ana-digi sports watch: an LCD for the month, day, hour, minute, second and weekday, plus two hands driven by two separate motors — a time motor on two pins that carries the hands you read as the time, and a speed motor on three pins that drives the speed indicator. Its feature list runs to a stopwatch with SPL and LAP recording, a 24-hour countdown, world time for 48 cities, four daily alarms plus a snooze, and an EL backlight.
This page follows the operation leaflet that ships with the watch, in the leaflet's order. Four keys run everything — A, B, C and D — and the same key does different things depending on the mode you are in, so the first section is the key table.
What the leaflet lists as features:
- Timing function, display month, day, hour, minute, second, week
- 12/24 hours format
- Calendar range: fully automatic calendar from 2000 to 2099
- Stopwatch (SPL, LAP) — with a specified distance it also calculates and displays speed
- Countdown, timing range 00:01'00" to 24:00'00"
- World time: time of 48 cities (29 time zones)
- Daylight saving time / standard time, local city / world city switch
- Alarm function, including hourly alarm, daily alarm and intermittent alarm
- EL backlight with an automatic lighting function
- Dual motor indicator: speed motor on three pins, indicator 0–98 (only even numbers); time motor on two pins, indicating the time

The four keys
The leaflet names each key after the job it does outside a setting screen: A is RESET, B is LIGHT, C is MODE and D is START.
| Key | Name on the leaflet | What it does |
|---|---|---|
| A | RESET | Held for 3 seconds it opens the setting screen; a short press leaves it, clears the stopwatch when it is stopped, returns the countdown to its set value, and turns the alarm, snooze and signal on or off in alarm mode |
| B | LIGHT | Lights the EL backlight; inside a setting screen it changes the flashing value |
| C | MODE | Moves to the next mode; inside a setting screen it selects the next item to set |
| D | START | Starts and stops the stopwatch and the countdown; switches the display between time and date; changes the value; held for 3 seconds it opens the hands' base-position correction |
Switching modes
Press C to walk the five modes in one direction: Time, Stopwatch, Countdown, World time, Alarm, and back to Time. The top line of the display changes with the mode — the weekday in time mode, the city code in world time (CAI for Cairo on the leaflet's sample screen), AL1 in alarm mode.
Setting the time, the city and the date
Hold A for 3 seconds in time mode until the city blinks. C then steps through ten items in this order, and B or D changes whichever one is flashing — hold either key down to run the value quickly. Press A again to leave the setting screen.
| Step | Item on the display | What it sets |
|---|---|---|
| 1 | "city" | The local city, which also fixes the time zone for world time |
| 2 | "summer time (off/on)" | Daylight saving time on or off |
| 3 | "12/24 hours" | The display format |
| 4 | "seconds" | The seconds |
| 5 | "EL time" | Listed by the leaflet under this name only; it gives no values for it |
| 6 | "day" | The day of the month |
| 7 | "month" | The month |
| 8 | "years" | The year |
| 9 | "the minute" | The minutes |
| 10 | "hour" | The hour |
The order is the one place readers get caught out: the hour is the last item, not the first, and the city comes before everything. Leave the screen before you reach the hour and the clock stays wrong.
Separately from all of that, D in time mode switches the display between the time and the date, and back.
Setting the hands to their base position
If the hands disagree with the display, correct their base position rather than the time. Hold D for 3 seconds in time mode, then press C to move between the two motors — the leaflet's cycle is speed motor, time motor, speed motor.
With the time motor selected, D moves the hand clockwise one step, and holding it for 2 seconds turns it quickly. With the speed motor selected, D moves the speed-indicator hand one step clockwise. Press A to leave the mode, and the pointer synchronises with the time automatically.
Stopwatch: SPL and LAP
Press C once from time mode. The stopwatch range is 0–99 hours 59 minutes 59.999 seconds, D starts and stops it, and A clears it once it is stopped. The leaflet then gives four separate sequences, split across the two recording modes and single or multiple recording.
| Mode and recording | Step 1 | Step 2 | Step 3 | Step 4 |
|---|---|---|---|---|
| SPL, single record | D — start | D — stop | A — clear | — |
| SPL, multiple recording | D — start | A — controls stop and restart of the timing | D — stop the timer while it lasts | A — clear |
| LAP, single record | D — start | D — stop | A — clear | — |
| LAP, multiple recording | D — start | A — closes the first period | A — starts or ends each following period | D — stop, then A — clear |
Press A to change between SPL and LAP. In both modes the single record is the same three presses, and the difference only shows up in multiple recording: SPL uses A to stop and restart the timing, LAP uses A to close one period and open the next. The leaflet gives the two sets of presses but does not describe how the two readings differ on screen.
Countdown timer
Press C twice from time mode. The countdown runs from 00:01'00" to 24:00'00", D starts and pauses it, and once it has been paused A returns it to the original set value. When the countdown ends it beeps for 10 seconds.
To set the start value, hold A for 3 seconds in countdown mode; the hour flashes. C selects the item, B or D changes it, holding either key adjusts quickly, and A leaves the setting screen. Two small symbols in this screen choose what happens at zero: one means the timer returns automatically to the initial set value, the other means it counts down again in a cycle.
World time
Press C three times from time mode. D selects the city and holding it scrolls quickly; A shows the date and returns to the time display after 2 seconds.
The watch carries 48 cities across 29 time zones, and the leaflet prints them as three-letter codes on the display — HNL, PPG, ANC, YVR and so on. The code map below is the leaflet's own list, one row for each group of four cities.
Alarm, snooze and signal
Press C until the top line reads AL1 — the alarm is the fifth mode, four presses from time mode. A switches the alarm, the snooze and the signal on or off, and the display says ON when the selected one is on and OFF when it is off.
D moves between the four alarms and the two extra functions in this order: SIG (the hourly signal), AL1 to AL4, then SNZ (the snooze). To set one, hold A for 3 seconds until the hour flashes, use C to switch between hour and minute, adjust with B or D, and press A to leave.
If something looks wrong
Almost everything that looks like a fault on the 2101 is a setting screen or a mode the watch is sitting in. Each row below traces back to a sentence in the leaflet.
| What you see | What it means | What to do |
|---|---|---|
| An item is blinking and the keys do not do what you expect | The watch is in a setting screen, waiting for that item | Press A to leave the setting mode |
| The setting screen disappears on its own | No key was pressed for two or three minutes, so the watch exits by itself | Nothing is lost — reopen it with a 3-second press of A |
| The hands point somewhere other than the time on the display | The hands' base position no longer matches the display | Hold D for 3 seconds and correct the position; on exit the hands synchronise automatically |
| The alarm does not sound | The alarm is off — the display shows OFF | In alarm mode press A until it reads ON |
| World time shows the wrong city | Another city is selected in world time mode | Press D to select the city you want, or hold it to scroll |
