What would happen if we united imagination with knowledge? The first leads us to create an existing device, but with new purposes. The second characteristic, knowledge, allows us to provide it with specifications based on current technologies. This is how you can conceive the Huawei Watch Ultimate II, the same one that allows you to communicate underwater, in a special (and space) edition for astronauts to take to the Moon and Mars.
The first of them would be the Huawei Watch Ultimate II Moon Edition. This is one piece created for long-duration lunar missions and permanent bases on the satellite. Its function is not only to measure time, but to adapt to an environment where days last almost an Earth month.
It has a synodic mode: in addition to the lunar phases, The watch includes a 29.53 day synodic scale and EVA counting system (extravehicular activity) based on cycles of solar exposure and shade.
With this in mind A system of mission zones is added: it allows simultaneous synchronization of terrestrial time and lunar base time (such as UTC + Moon 0), with communication between mission clocks via satellite link.
It also includes a radiation and micrometeorite sensor: records exposure to energetic particles using a miniaturized dosimeter which alerts if the user exceeds the security threshold. Another of its sensors is the vacuum barometer: not to measure atmospheric pressure (non-existent), but to detect microleaks in pressurized suits or habitats through variations in relative pressure.
Regarding its construction, it has a sandblasted titanium case (aerospace grade) with reflective ceramic coating to resist extreme thermal changes. Added to that is a hybrid Nomex and Kevlar strap, in gray, with lunar blue inserts that evoke the faint glow of the regolith under the “full Earth.”
Micro-textured OLED display to reduce glare in direct sunlight without sacrificing visibility and animation of Real moon phases, with shadows calculated according to the user’s current position with respect to the Earth and the Sun.
For his part, the Huawei Watch Ultimate II Martian Pioneer Edition is designed for manned missions or Martian habitats, where a “sun” (Martian day) lasts 24 hours, 39 minutes and 35 seconds. The watch translates that difference (minimal, but essential for communications) into a new standard: “Sol Sync Mode”, which converts terrestrial time to Martian time in real time.
Regarding materials, it shares some characteristics with its selenite counterpart. Titanium case with copper PVD coating (to give it a “Martian red” touch), resistant to ferric oxidation from Martian dust.

In this case, the FKM strap is in rust red and volcanic brown tones, with vents inspired by dunes and tectonic fractures. The crystal is sapphire with an amber tint, for filter excess reddish light and improve readability under dust storms. To this it adds luminous elements in turquoise blue: a tribute to the underground ice and the ancient Martian riverbeds.
If we talk about the “Martian specifications”, it incorporates a Martian atmospheric mode: recalibrated sensors for ultra-low pressure, extreme temperature (-80°C to +20°C), and dust storms. For location, it uses a hybrid interplanetary GPS system: it combines inertial navigation and local beacons (basically), since there is no GPS coverage on Mars.
Regarding cartography, carries interactive topographic maps: they show in digital relief the most emblematic valleys, canyons and craters —Valles Marineris, Mount Olympus, Gale Crater—with coordinates from missions carried out by NASA rovers.
One of the most important sensors is the electromagnetic dust meter: detects accumulation of ferromagnetic particles in the sensors and activates self-cleaning by ultrasonic vibrationlike when it gets rid of water on Earth after being submerged.
To extend your battery, It is equipped with auxiliary photovoltaic energy: a solar ring integrated around the bezel partially recharges the watch during walks under the faint Martian sun. Both versions would have the usual sensors (heart rate, SpO₂, temperature, compass, barometer and would also share a communication system between them for emergencies, similar to the ability to send messages underwater of the Ultimate II, but adapted to its environment.
On the Moon it would be the “LunarMesh Comm System”. Due to the absence of an atmosphere, conventional radio waves behave very differently: there is no scattering, but no useful reflection or bounce. That’s why, The lunar version of the Huawei Watch Ultimate II would use a hybrid low-power laser optical communication system and surface ultrasound.
Each watch features a directional infrared laser emitter (the size of a camera sensor) that transmits short-range data—up to about 2 km with direct line of sight—between watches or suit nodes. In areas without direct vision (for example, inside habitats or caves), the watch would automatically switch to surface mode, transmitting sonic impulses through the ground (at frequencies of 20–40 kHz, inaudible), taking advantage of the fact that waves propagate well in the compact regolith.
Both modes are integrated into a self-organizing network called LunaMesh, where each watch acts as a repeater. If an astronaut is out of direct range, the message “jumps” from watch to watch until it reaches the recipient.
On Mars it would carry the “RedDust Quantum Mesh” system. Taking advantage of the fact that Mars does have an atmosphere (although often visited by dust storms loaded with particles that create interference), short-range communications must be very robust. The solution is a simplified quantum network combined with low frequency (VLF) communication and optical support when conditions allow.
Each watch includes a VLF transceiver (3–30 kHz), ideal for traversing dust and rock. These frequencies allow you to send pre-established messages, coordinates and vital data (pressure, heart rate, etc.) up to about 10 km, depending on the terrain.
Under optimal conditions (no storm), a directional optical module of entangled photons is activated, based on quantum transmission experiments already carried out between Chinese satellites (Micius). It is not about sending big data, but about validating identity and synchronization between clocks using preloaded quantum pairs.When multiple watches are active, they form a local communication network that extends the total range up to tens of kilometers.
