Isobrite is the world's first T100 tritium illuminated lightweight polycarbon
watch. The watch features a 10-year battery life, ultra scratch resistant
sapphire crystal, two tritium markers on the unidirectional bezel, and
200m (20 atm / 660 feet) water resistance.

Unlike ordinary tritium watches that use T25 tritium illumination, the
Isobrite watch uses ultra bright T100 tritium illumination. This makes it 4
times brighter than the competition! The T100 tritium glass tubes are
manufactured by Switzerland’s mb-microtec and are currently the
brightest and most advanced tritium illumination available on the planet.

In addition, while most polycarbon watches use mineral crystals,
ArmourLite made the Isobrite watch with an ultra scratch resistant
sapphire crystal. Sapphire is the same crystal material used on high-end
fine watches by Omega and Rolex.

The 47mm wide and 12mm thick case is made from a carbon reinforced
poly material which is exceedingly strong while being very lightweight.
The back of the case is made of steel with four screws. The push-in
crown is 4mm wide. The case also features a unidirectional ratcheting
bezel with two H3 tritium illumination markers.

The Isobrite watch features a reliable Swiss Quartz Ronda 715Li
movement with a 10-year lithium battery.

The watch comes standard with a 22mm black silicone band with the
Isobrite logo. The clasp is a steel buckle with the IsoBrite logo as well.

ArmourLite offers a 2-year international warranty on the Isobrite watch.
Please note that the Isobrite watch does not feature a shatterproof crystal like the watches in the ArmourLite collection.

Isobrite compared to the leading model on the market
Leading model
Cost of servicing over 10 years (replace battery, seal, water test)
$49 (once every 10 years)
$49 x 3 times = $147
Leading model is more susceptible to scratches and may require crystal
replacement at an estimated cost of $116 each time.
Because Isobrite is a polycarbon watch, it features a push crown instead of a screw
crown. Please note that it is not necessary to have a screw crown to maintain water
resistance. The watch features 200m (20 atm / 660 feet) water resistance.
