    Question about the Sea-Gull ST16 automatic movement...

    I recently found out my watch has the Sea-Gull ST16 movement can anyone tell me a little about it? Like what country manufactures it etc. and how good it is? I will post a pic of my watch too. For the record I kept track of the time on my watch compared to the official GMT time and it is roughly 5 seconds faster over a 7 day period which is fine with me but is that good? Thanks for any info everyone!

    I don't know much about the sea gull movements aside from the fact that they are in a lot of cases these days. I'd try asking over in the Chinese forum as sea gull is of that region.

    Good luck and welcome to the wonderful world of horology.

    I just ordered this watch today on Amazon for $49 during a lightning deal. How do you like it?

    The sea-gull st16 has proven to be a good and reliable movement and many watch enthusiasts who buy "affordable" watches are really pleased with it.

    Congrats with your new watch and wear it in the best of health!

    Sea-Gull is the world's biggest manufacturer of mechanical watch movements and it is indeed Chinese (like most things these days, even some those four figure watches have a whole bunch of Chinese parts). The quality of their movements varies a whole bunch because they manufacture and sell to just about everyone at every conceivable level of quality, from rejects sold to terrible replica makers to haute horlogerie movements worth tens of thousands of dollars.

    I don't know anything about Armitron and their quality standards, but you seem to have a fairly good one judging from the time it keeps, but really the only test is time. At the end of the day it's an entry level piece so I wouldn't worry too much. If you truly get into the hobby you'll be buying many, many more watches.

    edit: bonus cool thing! You see that tightly wound coil at roughly 12:30 on the dial? It's the mainspring and you can use it to judge how much power reserve the watch has left.

    Good point. But how do you know when it is getting low? I know it will look less tightly wound, but by how much? Or do you just kind of guess from experience?

    It was a one hour lightning deal. I posted it in the Chinese forum, but it didn't last long. $125 is about what an ST16 Seagull costs. I just lucked out.

    It's not a reserve indicator so it won't give you an accurate indication. Some watches have a meter on the face or caseback to indicate how many hours of reserve power are left. Most watches don't of course so seeing the mainspring in this case will only provide an approximate indication. Rule of thumb - a watch worn every day should keep working. Unworn and assuming it had a full reserve when unworn, most watches will keep working for approximately 38-42 hours before stopping.
