PHYLIDA SP-31 ST19 Mechanical Chronograph 40mm

The PHYLIDA SP-31 combines classic racing-chronograph styling with the character of a true hand-wound mechanical movement. At its heart is the Seagull ST19 mechanical chronograph, visible through the display caseback and operated through traditional chronograph pushers.

A 40mm stainless steel case, domed top-hat sapphire crystal and black multi-register dial give the watch a distinctly vintage motorsport-inspired appearance. The red-and-white outer minute track adds extra visual energy, while the surrounding tachymeter scale completes the traditional chronograph design.

Seagull ST19 Mechanical Chronograph

Unlike a quartz chronograph, the SP-31 is powered by a mechanical hand-winding Seagull ST19 movement.

The movement controls the central chronograph seconds hand and multi-register dial while giving the watch the tactile experience associated with traditional mechanical chronographs. Winding the watch manually becomes part of the ownership experience, while the display caseback provides a view of the mechanical movement inside.

Racing-Inspired Multi-Register Dial

The black dial uses a classic three-register chronograph arrangement with contrasting white hands and markings for clear readability.

A distinctive red-and-white racing-style minute track surrounds the dial, creating the strongest visual signature of the Tin dial version. Applied hour markers and green luminous material improve visibility in lower-light conditions.

The outer tachymeter scale reinforces the motorsport character and complements the chronograph layout.

Domed Top-Hat Sapphire Crystal

A domed top-hat sapphire crystal gives the SP-31 the elevated profile associated with vintage chronographs while providing the scratch resistance expected from modern sapphire.

The raised crystal is an important part of the watch’s retro appearance and contributes to the overall 14.5mm case thickness.

40mm Stainless Steel Case

At 40mm in diameter and 48.5mm lug to lug, the SP-31 delivers the presence of a mechanical chronograph without moving into oversized territory.

The solid stainless steel case is paired with a matching solid stainless steel bracelet, creating a substantial all-metal construction with an approximate total weight of 170g.

Display Caseback

Turn the watch over and the mechanical character continues through the screw-down exhibition caseback.

Rather than hiding the ST19 movement behind a solid back, the transparent section allows its mechanical architecture to remain part of the watch’s appeal even when it is off the wrist.

Why Choose the PHYLIDA SP-31?

The SP-31 is especially appealing for enthusiasts who want more than the appearance of a vintage chronograph. Its ST19 hand-wound mechanical movement provides the mechanical experience behind the design, while the sapphire crystal and stainless steel construction add modern practicality.

The 40mm proportions, distinctive racing minute track and exposed movement give it a combination of vintage chronograph character and contemporary everyday construction.

PHYLIDA SP-31 vs Other Chronographs

For a different dial layout with the same hand-wound ST19 character, see the PHYLIDA ST19 Reverse Panda Mechanical Chronograph. It uses the same movement family but delivers a contrasting reverse-panda aesthetic.

Buyers who like the mechanical chronograph concept but prefer automatic winding should also consider the FARASUTE Trackmaster I Automatic Chronograph. Its 39mm case houses an automatic column-wheel chronograph movement, eliminating the need for daily hand winding.

For a more affordable chronograph with quartz accuracy, the Baltany S205034 Vintage Chronograph uses a Seiko VK64 meca-quartz movement in a compact 39mm vintage-style case.
