Apparently, this is a 650 nm laser watch that monitors blood pressure, pulse, and blood glucose levels. One such watch by a Chinese firm called Joom is on sale now, In the small print, the OEM declares this item should not be used for diagnosis or treatment of any medical condition. Suggests that it is not yet reliable enough to use as a serious contender for conventional instrumentation. It is expensive to purchase the cheapest price on the internet that I saw was £165.
I remember that my old University department was researching this technology, but was unable to produce a practical instrument for sale, There was another company set up to sell a similar device, but that was closed down and the directors were indicted for fraud since the laser turned out to be a commonly available non lasing LED diode.
There was also the AKBQ laser therapy watch being sold on Amazon, but it is not available at the moment. The item description of it on the Amazon site is indeed suspect. They claim it aids in the treatment of diabetes but do not mention glucose monitoring. It's size reminds me of the early mobile phones and not elegant at all
I will let others seek these items out since I do not feel they are worthy of posting on this site.

Samsung and apple are both claiming that they will have glucose sensing technology in their next generation of watches. Discussion here

The OP is specific to Bloodwatch-laser, which is not as far as I can see connected with either of the firms you mention and which is being discussed in that other thread.
We must be careful. I have seen claims that are obviously hard sell for commercial gain targeting a captive audience who have health issues, and who will pay large sums for new technology in the hope of finding solutions. These people are vulnerable, and I have a great distrust of what I have so far seen for the Bloodwatch technology which not only measures blood sugar and blood pressure but apparently is claimed to also measure cholesterol, blood fat content and also cure (yes CURE) blood disorders and prevent CVD and thrombus by making the blood thinner. Simply by shining a light on the skin. Sorry if my skepticism is showing.
The last time I saw this sort of thing was a bomb detector that doubled up as a drug detector for customs officers and made a fortune for the scammers. Amazing what you can do with an impressive empty box and a couple of coat hangers. And it was several years before anyone took it apart to see how it worked. When something is offered as a cure-all for multiple purposes all of which are safety involved, then I get nervous.
I have an oximeter that measures blood oxygen levels. It too uses light technology but is believable because haemoglobin does change colour according to saturation, so using light in this technology is feasible. It is not particularly accurate though and it is position and pressure sensitive.

As regards the Apple watch
"The new Apple Watch is able to use an app that can monitor blood glucose levels. The app was designed by DexCom and can track and display glucose levels in the form of a graph. DexCom's glucose monitor will take the form of a body sensor that you wear around your abdomen." No mention of lasers
Edit to add There are rumours of an Apple iWatch7 Active that may have laser technology.
The Samsung new watch does use laser technology and is actually based on the technology that my University was working on, but which they abandoned soon after I donated to their research program for it. The problem with using semiconductor lasers in what is essentially a mass spectrometer is that their frequency drifts for so many reasons, and it is difficult to get reliable filters and refractors to decode the signals returned with any conviction. We think test strips are bad at 15% error, but lasers weren't any better. That's before they go for mass production. So, maybe Samsung have cracked it. They are certainly moving into the medical field now along with robotics, and their ability to place all the components onto the same slice of silicon will help design feedback loops to compensate for many things, such as temperature and pressure.
