Age Estimate
Circa late 1960s to early 1970s production based on the dial typography, case geometry, and bezel style
Cultural Significance
Representing a foundational pillar in the history of scuba diving instruments, the Sea Wolf democratized underwater timekeeping for civilian and military divers alike, cementing its status as an essential mid-century tool watch.
Condition Notes
Very Good vintage condition. Case shows light signs of wear with minor desk diving marks consistent with age, but retains sharp lines. Dial is remarkably clean with well-preserved lume plots and hands. Bezel insert is intact with minor aging. Crystal shows faint hairline scratches typical of acrylic, which can be easily buffed out.
Value Estimate
Estimated secondary market value ranges between $1,200 and $2,500 USD, heavily dependent on the originality of the dial, condition of the Bakelite bezel, and presence of original box, papers, or matching steel bracelet.
Care & Maintenance
Requires careful handling due to vintage status. Keep away from strong magnetic fields and moisture until pressure-tested by a certified watchmaker. Recommended full mechanical service every 4 to 5 years. Avoid exposing the vintage acrylic crystal to harsh chemical solvents.
