I am looking at purchasing a Parnis GMT. Relatively inexpensive @ $75.00. It is supposed to have a "2813" movement. Does anyone here have any experience with this movement or brand?This will be my first foray into a Chinese movement watch so I need some help.Thanks,Anthony

Problems with AP RO 15400!
Hi everyone. My newish AP RO 15400 has an issue. One of the screws on the front face seems to have come loose. The screw sticks up above the bezel. (it's the screw at the 4) I don't want to try to screw it back as these screws are high polish and the bezel seems to be cut for the screws. Should I just take it to the boutique? I bought it on the grey market but it was purchased from a boutique in October of 2012.Could this affect the water proof seal? Thank you.

Speedmaster differences - help please
Hello...posted a couple of previous posts , but now I am pretty close to pressing the button on a Speedmaster - one problem though - there is a few of them , and since the shops do not have most of them , its only looking at pics and specs on websites - and ofcourse your helpFirstly the relevance of the professional in a speedmasterAlso , what are the major differences between these3210.50.00 0 -40mm so slightly smaller than others but I think it will do, has date , but is automatic at a good price - the face looks like it has a lighter black circle in the middle ( GBP 1560 )3220.50.00 - has day too , otherwise very similar to above , GBP 1810 )3570.50.00 - Cheapest Pro , same price as above , no date , 42mm , ,manual wind which in my eyes is a small negative ( GBP 1920 )311.30.44.50.01.002 - the Pro , 44mm , co axial system , still not sure if it means same as automatic but I think both are movement wound , the Pro face seems slightly cleaner and it has a glass back , GBP 2870311.30.4

One out - One in 🐼
This is a move I’ve been strategizing and planning for several months. It took me a while I finally got the right numbers and example in place, thanks to my main man Takuya!This is another example, of one amazing watch leaving for one arriving. Loved the black dial Daytona. I still maintain that it is the more versatile of the two, but the white dial has been constantly haunting me. I had to try it, and couldn’t pass up this opportunity to do so.Here ya go my friends. My new 116500LN White Dial Daytona!
