Tier One – Thunder Tactical Watch – GROM

Thunder is a digital tactical watch face for the night jump: the time in big stencil digits with its military time zone letter, the moon, first and last light and your data, all turning red when night falls. Part of the Tier One series, it is inspired by Poland’s JW GROM, the unit that carries the name of the Cichociemni, the Home Army paratroopers who jumped into occupied Poland by night.

THE DISPLAY
• The time in big stencil digits inside a target box, with the seconds while the screen is awake
• The military (NATO) time zone letter beside it: B for Warsaw in summer, Z for UTC, E* for India
• The date with the white-over-red mark
• Minute ring with a red seconds tick, and the watch battery at 6
• Graphite or light dial, with the diving eagle of the GROM badge in the background (can be turned off)

MOON AND LIGHT
• The moon lit as it is now, its illumination and its next rise or set
• Today’s light from midnight to midnight: night, nautical twilight and day, with the current time
• First and last light (BMNT and EENT): the start and end of nautical twilight, as military planners use them

RED NIGHT VISION
• From last light to first light the whole face turns red to keep your eyes adapted to the dark, and also while the watch’s night mode is on
• Or keep it red all the time, or turn it off

YOUR DATA
• Three data fields, altitude, Pulse Ox and heart rate by default, each with 34 choices: next sunrise/sunset, sunrise, sunset, steps, steps and goal, distance, calories, floors, elevation gain, intensity minutes (day or week), heart rate, resting heart rate, Pulse Ox, Body Battery, stress, respiration, recovery time, VO2 max running or cycling, training status, weekly running or cycling distance, next calendar event, altitude, pressure, air or sensor temperature, humidity, chance of precipitation, feels like, UV index, dew point, solar input

BUILT FOR YOUR SCREEN
• AMOLED: dimmed, shifting always-on mode with the stencil time and the moon, red at night, designed for Garmin’s burn-in rules
• MIP: every color picked for the 64-color screen, the whole face always on

THE TIER ONE SERIES
Four watch faces, each inspired by a different special forces unit and each with an idea of its own: Thunder, a night-jump tactical display; Frogman, the dive watch of the Navy SEALs; Sabre, a field watch that finds north by the sun; Satory, a precision reticle. All four are in the Connect IQ Store: look for “Tier One” to complete the set.

WATCHES: 69 round Garmin models of the fēnix, epix, MARQ, Forerunner, Venu, vívoactive, Enduro, Instinct, Approach, D2 and Descent families (all listed on this page).

LANGUAGES: English, Polish, Spanish, German and French.

GOOD TO KNOW
• Data that needs a sensor or feature your watch does not have (for example Pulse Ox or a barometer) shows “–“.
• Until the watch knows a position (a GPS activity, or weather from your phone), first and last light and the moon’s rise and set show “–:–“, and red night vision follows the clock: 20:00 to 06:00.
• Thunder is an independent design, not affiliated with or endorsed by Jednostka Wojskowa GROM (JW 2305) or the Polish Ministry of National Defence, which established the GROM badge as the unit’s official insignia, nor by any other military unit or government, or Garmin.

PRIVACY: Thunder has no server, collects no data and sends nothing anywhere: everything stays on your watch.
