Enicar Healthways 100 Fathoms

Partially verified

This Enicar Healthways 100 Fathoms is a stainless steel wristwatch produced in 1955. It features a 35mm case characterized by its turtle lugs and an Enicar-signed crown. The dial is co-signed with the American dive gear manufacturer Healthways and displays a glossy gilt finish that has developed a brown and gold tropical patina with visible surface spidering. It uses radium-based luminous material on the dial plots and the original candlestick second hand. The timepiece houses a movement utilizing the Ultrasonic cleaning and lubrication process, a technological innovation developed in Oensingen, Switzerland, to improve movement longevity by preventing lubricant diffusion. The watch is presented on a two-piece handmade leather strap. While shareable in design with the Seapearl 600 model, this specific example was marketed by Healthways for use in diving applications.

Object description

Case and Dial Design

The watch features a 35mm stainless steel case defined by distinctive turtle lugs. The case exhibits signs of past polishing while maintaining its original factory dimensions. It retains the original Enicar-signed crown and has a case back with original factory engravings.

The dial is a glossy black gilt example that has developed a tropical patina, showing striations of brown, gold, and silver. Age-related spidering is visible across the surface. Luminous markers at the hour positions and the original candlestick second hand contain radium lume, which has aged to a sandy tan color. The dial bears the dual branding of Enicar and Healthways.

Evidence for this section
  • “The unique and early turtle lug case is in excellent condition”
  • “The original glossy gilt dial has achieved a beautiful tropical patina”
  • “These gems feature the always charming "turtle" lugs and have beautiful dials that are co-signed with Healthways.”

Movement and Technology

The watch incorporates the Ultrasonic technological procedure developed in 1953. This process, created by the Federal Institute of Physics in Zurich, utilized ultrasonic waves to clean movement parts prior to assembly.

A specialized chemical coating was also applied to the movement components. This application was intended to prevent the diffusion of lubrication, ensuring it remained in specific designated areas to improve the movement's lifespan and service interval.

Evidence for this section
  • “Many Enicar watches host the word ‘Ultrasonic’ beneath the iconic Saturn logo”
  • “The 'Ultrasonic' process was designed by the Federal Institute of Physics in Zurich. The method was used to clean watch movement parts before assembly, using ultrasonic waves.”
  • “The coating prevented lubrication from diffusing throughout, which kept the lubrication in its intended locations within the movement.”

Historical Context and Attribution

This timepiece was specifically produced for sale by Healthways Scuba, an American diving equipment manufacturer. Although not technically identified as a Seapearl model, it utilizes the same case and movement construction as the Seapearl 600.

The Seapearl 600 model gained associations with United States Navy divers during the late 1950s. While not issued equipment, these watches were included in official performance tests alongside other prominent diver's watches of that period.

Evidence for this section
  • “this Healthways 100 Fathoms from Enicar isn't technically a Seapearl, it does share the same case, movement, and almost the same reference number.”
  • “it is essentially the same model as the Seapearl, but was specifically made for and sold by Healthways Scuba”
  • “the Enicar Seapearl 600 was also popular with U.S. Navy divers even though they were in (non-issued).”

Open research questions

  • What is the specific movement caliber utilized in the 100/61-10 reference?
  • Are there any surviving production records indicating the total number of Healthways-branded Enicar units manufactured?
