The quick answer.
SEA-GULL 1963 Series Original D304 Sky Voyage Edition 40 mm is a manual chronograph watch with case dimensions Approx. 40 mm diameter × 46.2 mm lug-to-lug × 14 mm thick at $789. We recommend it for a buyer who wants a hand-wound chronograph with a heritage-led dial, sapphire crystal and a 40 mm case.
Why it belongs on the shortlist.
The Sky Voyage offers a more polished, beige-dial take on the 1963 story. The red central hand adds a clean point of contrast, and the two registers keep the chronograph layout readable. We like it as a considered dress-casual watch for someone who enjoys winding a mechanical movement and wants the movement itself to be part of the experience.
A heritage chronograph with a distinct Sky Voyage dial.
SEA-GULL presents the D304 as a 1963 aviation reissue. This beige version pairs a sunburst-style dial with a red central chronograph hand and two registers, creating a softer, more refined alternative to the familiar cream-and-blue Times Edition. The dial has plenty to explore without losing its main time display, making the watch a strong fit for someone who wants a mechanical chronograph with a story behind its design.
The ST1901 makes winding part of the appeal.
SEA-GULL lists its ST1901 manual-wind chronograph with 22 jewels and a 21,600-vph frequency. The brand describes an approximate 37–45 hour power-reserve range. A hand-wound movement asks for a regular winding routine, but it also gives the owner a direct connection to the watch’s mechanical character. We have not measured this example’s timekeeping or reserve, so those remain manufacturer specifications rather than test results.
Check the full case span, not just the diameter.
The listed case is approximately 40 mm across, 46.2 mm from lug to lug and 14 mm thick. That combination gives the D304 a balanced but noticeable profile. The 20 mm leather strap and pin buckle complete the traditional look. Compare the full dimensions with a watch you already enjoy, especially if you prefer a thin case or a shorter span.
Sapphire and steel meet a deliberately modest water rating.
SEA-GULL specifies a synthetic sapphire crystal and a 316L stainless-steel case. The product page lists 3 bar water resistance, which keeps the ownership brief focused on everyday dry wear rather than swimming. We treat that as a manufacturer rating; there has been no independent water test. The listed two-year warranty is also subject to the brand’s current terms.

Before you choose
This is a manual-wind watch: it needs regular winding and does not offer automatic winding. SEA-GULL lists a 3 bar water rating, so it is not the choice for swimming or water sports. At about 14 mm thick and 46.2 mm lug-to-lug, it also has more wrist presence than the 40 mm diameter alone suggests. The listed reserve range is approximate and has not been independently measured.
Who it suits.
A buyer who wants a hand-wound chronograph with a heritage-led dial, sapphire crystal and a 40 mm case.
When to choose something else.
Choose an automatic watch if you do not want a winding routine, or a higher-rated sports watch if regular water exposure is part of the plan.
Warranty, returns and ownership.
SEA-GULL lists a two-year warranty for the D304. Check the current warranty terms and care guidance before ordering. The 3 bar rating is modest, and the movement is manually wound; plan for the daily routine and keep the watch away from swimming and water sports.
