Sure, you can get a plain Jane Bioluminescence from the current Aragon catalog, but good luck finding the rare skeletonized version seen here. This classic piece was created before the name changed from Android to Aragon and features minimal branding.

The star of the show here is lume, so let’s start there! The Android Bioluminescence is lumed in places a watch didn’t know it could be lumed. From the inside out, there is lume material applied in a way that makes for a cool look with the lights on or off.

The 316L stainless steel case is a large 50mm diameter with a thickness of 15.5mm. Lug-to-lug spans 53mm across the wrist. It’s a big and heavy piece, that’s for sure, but it’s an Android after all!

The integrated bracelet means you won’t be swapping straps on this one. Luckily, the bracelet has a decent built quality with satin outer links and polished center links with 4 lume rectangle accents per link. Get it on and off your wrist via the same sturdy locking double-push button clasp found on many Android/Aragon pieces.

The caseback is simple with the reference number AD660 in the center. Android is good about being informative on the back, without being overly cluttered. Although, some might think it’s a bit cheesy to have an email address on the caseback… but how many other watch companies are confident enough to put a point of contact directly on their watches?

To take full advantage of the glowiness, be sure to charge your Bioluminescence before heading out to a concert or party. If nobody else thinks it’s as cool as you do, at least your friends can find you in a crowd – just wave your wrist in the air like you just don’t care. No lighters needed!

Lume, lume, lume, even the crown is lumed. It’s a screw-down crown, assisting in the watch’s 200m/660ft water resistance rating.

You may have noticed that there is lume glowing through the skeleton dial from the inside. How did they do that?! It has a lumed sticker-like object on the inside of the caseback. This glowing backdrop is another feature that does not appear to be included in the design of the newer Aragon version.

Powering the Bioluminescence is a made in China Seagull caliber TY2809 skeleton dial. Caliber Corner has all of the deets on this engine here, but the TL:DR is that the TY2809 (aka ST1601K3) has 21 jewels, beating at 21,600vph, with a power reserve of 36 hours (somewhat low by today’s standards).

It is a true no date with one crown position for time-setting. Incabloc anti-shock as seen below. The TY2809 is hand-windable and has hacking seconds.

Minimal branding is located on the tiny sliver of dial that exists around the skeletonized view inside.

Overall it is a fun timepiece that will be unlike anything else in your watchbox, and unlike anything else you’re bound to see out in the world. If unique is your thing, this is your watch. The only downside is that they are hard to find – at least the Android versions with skeleton dials, but that is the one you want! The example in this watch review was sold almost instantly upon being listed in the watch shop.
