TOPHILL TL027G 40mm Seagull ST1901 Manual-Wind Chronograph

TOPHILL TL027G 40mm Seagull ST1901 Manual-Wind Chronograph

The TOPHILL TL027G brings vintage chronograph styling to a 40mm hand-wound mechanical watch. Its textured dial, leather racing strap and visible movement give the model an engaging character for everyday wear and for a collection focused on traditional watchmaking.

Mechanical movement

The Seagull ST1901 is a manual-wind column-wheel chronograph movement. The crown supplies winding energy, while the chronograph controls operate a separate elapsed-time display. A transparent rear window allows a view of the mechanism, including its moving components and finishing.

Case and materials

The 316L stainless steel case is listed as 12.4mm thick. Flat sapphire crystal protects the dial, and the detailed source specifications also list a sapphire viewing window in the screw-down caseback. A push-pull signed crown completes the case design.

Dial and wearing details

A sandblasted dial finish provides texture beneath the applied markers and luminous hands. The quick-release genuine leather strap tapers from 20mm to 18mm and fastens with a pin buckle. The combination of a compact case and a racing-style strap gives the watch a distinct vintage-sports appearance.

Everyday use and care

Water resistance is listed as 5ATM / 50M. Follow the manual for winding and chronograph operation, and protect the leather from prolonged wetting. The supplier explicitly states that the earlier Milanese-bracelet promotion has ended: the current listing includes the leather strap only.
