OUR TAKE

The "Chinese movement" grumble shows up under every Baltic listing on Reddit and WatchUSeek. The Sea-Gull ST1901 is the Venus 175. Same architecture, same column wheel, sold to Tianjin in 1961 to power Chinese military chronographs — the calibre that sat inside Universal Genève Compaxes and Eberhard Extra-Forts now going four-to-five figure at Phillips. 36.5mm wears closer to 38 because the lug-to-lug is 46mm. Under 6.75" wrist it's right. Over 7.25" you'll think you're wearing a dress watch.
