The Seagull is a Venus 175, aside from the gearing of the chronograph second wheel, they are exactly the same.
They are not delicate, but they seems to be more sensitive to proper adjustment... maybe Ron can add in some thoughts.
My thinking is that the movement is a solid design but it's finicky enough that it surely counts who is doing the assembling: the various Sea-Gull 1963 versions from Tsinlien (HK Sea-Gull, not to be confused with Tianjin Sea-Gull) have had on-and-off issues but other well regarded assemblers/manufacturers (Precista/Perpetual for two obvious examples) and the Tianjin Sea-Gull D-304 and other Tianjin built chronos seems to hold up fine.
I'd still pick quartz or 7750 for heavy chrono use, though.
