Seagull

Seagull's complicated automatic caliber featuring moonphase and day-date displays in a single movement. At 6.8mm thick it accommodates the additional moonphase disc mechanism atop the base automatic platform. The 27-jewel count reflects the added complexity, and the moonphase display adds a touch of haute horlogerie to watches priced in the budget segment. Represents the most complicated mass-produced Seagull movement currently available.
