Background

B-cell activating factor (BAFF), also known as B lymphocyte stimulator (BLyS), is a cytokine that belongs to the tumor necrosis factor (TNF) ligand superfamily and plays a crucial role in regulating B-cell development, survival, and function. In humans, BAFF is primarily produced by myeloid cells, including monocytes, macrophages, and dendritic cells, and acts on B cells through binding to its receptors, BAFF-R, TACI, and BCMA. By engaging these receptors, BAFF promotes the survival, maturation, and antibody production of B cells, as well as the formation of germinal centers and the maintenance of peripheral B-cell populations. Dysregulation of BAFF signaling has been implicated in various autoimmune diseases, such as systemic lupus erythematosus (SLE) and rheumatoid arthritis, highlighting the importance of BAFF in immune homeostasis and autoimmunity.

Unique watch for sure
Color: Silver, Size: 15MM
So good, so cute. The face is pretty small but what do you want from a ring watch? I would say it is not for bigger fingers. I wear a size 7.5 and it fits perfectly. It does have an elastic band but when I tried it on a larger finger, it definitely pinched. I am of fan of different watches so this fits the bill. It's unique and an eye-catcher. Well done Fossil.

Pretty. Tiny. Hopefully has good battery life. UPDATE: The silver one was defective.
Color: Gold Raquel, Size: 14MM, Color: Gold Raquel, Size: 14MM
I bought both the gold and the silver ones. I have a collection of ring watches but most of them are sets you can buy for cheap. These are my first made by a well known watch company. They look big on picture but they are tiny. I bought it so when my smartwatch dies I have one on my ring to tell the time. I don't like going on my phone to check the time just to avoid distractions. I hope the battery lasts long. Updated review: I started using the gold one and it works great! The silver one wasn't working so I processed a return for it. However when they shipped the replacement, there was nothing inside the tin can fossil case. I called Amazon and they refunded me for the silver one. The product works great. I probably got a defective one. My fear is maybe someone took the ring before packing it for replacement. That's just wrong. I'm going to get the silver one from Macy's instead.

Cheaply made
Color: Gold Glitz, Size: 15MM
I really love the concept and honestly it’s super cute BUT the diamond around the face of the watch fell off within the first wear:/ so unfortunate because it has so much potential.

Beautiful watch, great packaging, but didn’t work.
Color: Silver, Size: 15MM
I love my ring watch so much that this is my second one (I washed my first one 😩). I ordered the ring on Wednesday and I got it Friday. I was so happy to get it, great packaging and fast delivery imagine how hurt I was when it didn’t work. I am gonna try to get a new battery and I pray that works but with the price being 80 plus dollars this should have never been a problem.
