What you need to know is that tritium will not shine as bright as high-quality lume (like C3 Super-Luminova), but when you compare the two after around 20 minutes has passed since the charging of the lume, you can expect the tritium tubes to be noticeably brighter – and, you can rest assured, they will stay that way. So, if you enjoy the bright, vibrant glow of freshly charged lume, then tritium may not be what you are looking for – but if you want to be able to read the time early in the morning or 2 hours into a movie in the cinema, the latter is your best bet.
The centerpiece of the Sîn, without a doubt, has to be its highly unusual sun-moon display. What we're looking at here is effectively a 3D day/night indicator – to get a better idea on how it works, check out the video above and see it in action. The passing time is recorded by centrally-mounted hands (the hour hand is referred to as "eccentric" as it appears to float above a silver colored ring surrounding the minute hand). The center has a small minute display while the hours are indicated at a somewhat larger scale with a dew drop shaped hand.
