Background
Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is a type I transmembrane glycoprotein and a member of the CEA family. The extracellular domain of CEACAM1 consists of a membrane-distal immunoglobulin (Ig)V-like N-region and variable numbers of alternating IgC1- and IgC2-like proximal regions. Therefore, this molecule is also classified as a member of the Ig supergene family. Several heterophilic ligands for the N-domain of CEACAM1 have been reported. However, homophilic ligation of the N-domains of CEACAM1 with another N-domain of CEACAM1 is the predominant means of physiologic interaction. CEACAM1 has been reported to be involved in several functions such as tumor growth, angiogenesis, endocrine function and immunology in humans and rodents.

Great watch
Color: Green
This watch is two times the price of the he casino watch but it is so much better. The indigo dial lights up completely from all angles. It is easy to read even in 0 light. Much more durable and runs on 1 battery instead of 2 batteries in the Casio. Can’t go wrong with this watch!!!

First watch was defective, Replacement is great
Color: Green
It says indiglo on the watch face but there is no illumination what so ever. Totally useless in the dark. I exchanged it for a new one and it is perfect. Just what I expected. I can't speak to its accuracy yet, but it looks and feels great. The bezel doesn't move if that is important to anyone, but I don't think anyone is taking this scuba diving.

Worth it
Color: Orange
Excellent for the price. The indiglo is highly visible as a backlight. It's simple and no frills. The band is better than I expected. I gave it 4 stars because it's only water resistant to 100m or 10ATM and the adjustment/indiglo button isn't flush with the case. Overall Excellent choice for an outdoors watch.
