Brand
Ermano (Ermano SA). A mid-tier vintage Swiss brand from the Bienne/Solothurn region. They were known for solid reliability but did not survive the Quartz Crisis in their original form.
Movement
Automatic/Self-winding mechanical. Likely houses a Swiss workhorse caliber such as an ETA 2783 or an AS (A. Schild) movement common to Ermano from this era. Typically 17-25 jewels with a 42-hour power reserve.
Dimensions
Case diameter: 36-38mm, Thickness: 12mm, Lug-to-lug: 42mm, Lug width: 18-20mm. It wears larger due to the thick bezel and cushion-style case profile.
Description
The Ermano Lunastar is a quintessential example of 1970s 'affordable luxury.' It mimics the aesthetics of high-end Swiss brands like Rolex or Omega but utilizes more accessible materials and movements. Its chunky scalloped bezel and 'star' branding reflect the optimistic design language of the Apollo-era watch market.
Key Features
Distinctive scalloped/serrated bezel; 'Lunastar' model name; Bold 3D applied indices; Tritium lume markers (indicated by T markings); Integrated cushion-style lugs.
Dial Description
Sunburst gold dial with significant age-related spotting (patina/foxing). Features oversized chamfered rectangular indices, thick baton hands with possible tritium strips, and a framed date window at 3 o'clock. 'LUNASTAR' lettering at 6 o'clock.
Case Material
Gold-plated base metal (likely 10 or 20 micron plating). The finishing is largely polished brass/plating with significant wear on the lugs and edges revealing the base metal beneath.
Crystal Type
Domed Acrylic/Hessalite. Shows heavy scratching and 'crazing' (micro-cracks) due to age and lack of polish.
Bezel Details
Fixed fluted/scalloped bezel made of gold-plated metal. The design is intended to play with light, similar to the Rolex Datejust, but with a more aggressive 1970s serrated pattern.
Crown & Pushers
Small, recessed push-pull crown at 3 o'clock, likely original but shows heavy wear and brassing.
Bracelet or Strap
Missing/None shown. Originally would have likely come on a gold-plated expanding Speidel or a leather strap with a gold-tone buckle.
Caseback Details
Screw-down solid stainless steel caseback. Usually features the Ermano logo, reference numbers, and 'Water Resistant / Swiss Made' engravings.
Movement Type
Automatic/Self-winding mechanical. Likely houses a Swiss workhorse caliber such as an ETA 2783 or an AS (A. Schild) movement common to Ermano from this era. Typically 17-25 jewels with a 42-hour power reserve.
Water Resistance
Originally rated for 3-5 ATM (splash resistant), but should currently be treated as having 0 meters of water resistance due to age-related seal decay.
Origin & Provenance
Swiss Made. Manufactured in Switzerland using Swiss-sourced components (ébauches) and cases during the peak of the independent mechanical era.
Age Estimate
Circa 1968-1974 based on the 'Lunastar' branding which capitalized on Space Age marketing and the use of 'T-Swiss Made-T' (tritium) at the dial base.
Cultural Significance
Represents the 'Everyman's' Swiss watch of the 1970s. It stands as a testament to the era before brand consolidation, when dozens of small Swiss firms produced watches for local and international markets.
Condition Notes
Fair to Poor. Significant plating loss (brassing) on the case and bezel. The dial shows moisture damage/spotting. The crystal is heavily scratched. Movement health is unknown and likely requires a full overhaul. Lume is likely inert.
Value Estimate
$50 - $150 USD in current 'as-is' condition. Refurbished specimens might reach $300, but the cost of service often exceeds the market value of the watch.
Care & Maintenance
Requires a full movement service and ultrasonic cleaning. Avoid all water exposure as gaskets are likely perished. Crystal can be partially restored with Polywatch, but replacement is recommended.

Interesting Facts
Ermano was part of the broad ecosystem of Swiss brands that provided high-quality mechanical watches before the Japanese quartz influx. The 'Lunastar' name was often used to imply precision or a connection to the celestial-obsessed culture of the late 60s.
