Hi Peteo, thank you for the interest, I don't have a cam with me part from my phone so I snapped one and borrowed another from the net to show the blue hands and screws on the bridge:
It is SEA-GULL M172s, and 100% CHINA MADE (every single bit including the box and papers

).
Spec:
Automatic movement (ST25),’ flywheel mechanical’
Power reserve indicator
Retrograde date
‘Flywheel’ at 6 o’clock position
38 jewels
Sapphire crystal front
Transparent back
Polished steel (316L)
Leather strap with folding buckle in steel
Diameter: 40 mm;
Water resistant to 5 ATM (50 meters)
It's 2 days old and running at +14s/day

, but ST25 tends to require some running in. I will give it a week to settle in and if lucky enough the public benchmark for a proper ST25 should be +5s/day
