The dial of the watch is striking and easy to read, with tritium tubes on the hands and hour markers that glow in the dark, making it easy to read the time in low light conditions. The watch also features a date display at the 3 o'clock position, adding to its functionality.

Tritium tubes, are small glass tubes that are filled with tritium gas and coated with a phosphorescent material. 

Tritium is an isotope of hydrogen that emits low-energy beta particles, which can be safely contained within the glass tubes. The tritium gas reacts with the phosphorescent material inside the tubes, causing it to emit light without the need for external energy sources.

Tritium tubes have several advantages over traditional luminescent materials such as super-luminova or Swiss-made BGW9. Tritium tubes do not require charging from an external light source, which means they are always emitting light and do not need to be "charged up" before use. They also provide a consistent and long-lasting glow that can last for up to 25 years, making them ideal for use in watches that are used in low-light or dark conditions.

Overall, the Vostok-Europe NH35A-575A279 automatic watch on a bracelet is a highly functional and stylish timepiece that is designed to withstand even the toughest conditions. It is a great choice for individuals who are looking for a reliable and versatile watch that can be worn in any situation.

Once you get the Energia watch on your wrist, you won’t want to take it off.
