You're welcome.
The Bell Dive helmet on the rear of the case is a trademark of Ervin Piquerez S.A., developer of the sealing technology of the screw back case. Basically the deeper the watch goes the more pressure is placed on a seal. Most were rated to 600', Bulova pushed that limit to 666' with these watches.
In the Dive community this watch would be referred to as a Single Crown Super Compressor.
