Background

B-and T-lymphocyte attenuator (BTLA) is also known as B-and T-lymphocyte-associated protein, CD antigen CD272. BTLA is a inhibitory molecule which belongs to the Ig superfamily that attenuates BCR and TCR-mediated signaling, and thereby functions as a negative regulator of lymphocyte activation. BTLA contains one Ig-like V-type (immunoglobulin-like) domain. As a lymphocyte inhibitory receptor, BTLA / CD272 inhibits lymphocytes during immune response. BTLA is not expressed by naive T cells, but it is induced during activation and remains expressed on T helper type 1 (T(H)1) but not T(H)2 cells.

Good budget watch
Color: 2926 Silver Stainless Steel/Black Dial
Good watch for a budget, color is good. The pins holding the link together tend to wear out and fall out. Other than that it worked good.

Nice Watch
Color: 5885 Siver Stainless Steel/hon Dial, Color: 5885 Siver Stainless Steel/hon Dial
Nice watch for the money. I've only had it a week but seems to be keeping good time. From 20 feet away might be mistaken for "Trump Time". The watch design is actually a copy of the Rolex Submariner for a whole lot less money. Several watch companies have copied the Submariner. I removed one link at a time when resizing the band. By the time I got to the final link, the supplied tool wasn't working. I had to remove the final link with a hacksaw and pliers.

DIDN'T LAST LONG
Color: 5885 Gold Stainless Steel/Gold Dial
Bought this in June 2025, and only wore it a few times. Recently noticed the time was "off" and the seconds-hand wasn't moving. I thought it sat too long and needed to be wound up. So, I wound...and wound...and wound. Never met any resistance in the crown during clock-wise winding...just continued to spin freely, and the seconds-hand never moved. It's a pretty-looking time piece, but don't waste your money if you expect it to keep time. 👎

Great watch, terrible resizing tool.
Color: 2926 Silver Stainless Steel/Black Dial
Watch is great, feel heavy, looks beautiful in person. It shines pretty heavily. My main issue is with the resizing tool it comes with. It broke when I tried to use it. Be prepared to buy your own like I did. I can’t say how the fit is yet because I can’t wear it yet. It is not easy to set up.
