The USB TO RS232/485/TTL is very easy to use, fully automatic transceiving without delay. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and/or applications with high communication requirement.
Features
1. USB TO RS232, USB TO RS485, USB TO TTL (UART)
2. Adopt original FT232RL, fast communicating, stable and reliable, better compatibility
3. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
4. Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
5. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
6. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
7. Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stably, without interfering each other
8. Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch
9. Aluminium alloy enclosure with sand blasting and anodic oxidation, CNC process opening, solid and durable
10. 3 LEDs for indicating the power and transceiver status
11. High quality USB-B and RS232 connectors, smoothly plug/pull

Unusable Adjustment Diagram – Completely Black
Color: Mesh Strap watch silver balck
The watch itself looks nice, but there is an issue with the instructions for adjusting the band. The included diagram is completely black and does not show how to make the adjustment.
I was only able to adjust the band because I had a diagram from a previous watch. Without that, it would have been very difficult.
The manufacturer should provide clear and readable instructions.

You won’t be disappointed with this one
Color: All Golden face Big Dial
Looks great fits great I was skeptical about getting it because I purchased another variation and was not happy at all but I like the way that this one looks so I said I’d give it another shot. I’m glad I did. I’m very impressed with it.

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly.
This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama.
Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh.
Size wise it was almost perfect. I just had to remove two links, nothing big.
It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one!
Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes.
So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder.
This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd.
The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.
