70s vintage watch mens swiss Adrem Mechanical Alarm Blue Dial Ronda 1223

Produced by the Swiss Endura Time Corp. This striking timekeeper features a vibrant blue dial with a dedicated red arrow hand for the alarm setting. Unlike standard vintage watches, this dual-crown piece houses a specialized manual-wind Swiss Ronda movement (identified by the 'RL' star stamp) featuring an integrated mechanical alarm complication.

Case:
o Metal chromed with back in stainless steel, marks and scratches all over
o Fine condition with strong geometry
o 35.5mm without crown / 42mm lug to lug / 11mm thickness / 18mm lug width

Movement:
o Mechanical Ronda 1223 - serviced by watchmaker on May 2026
(movement was disassembled, washed, lubricated) - photo of timegrapher
o Two crowns - The operational engineering of this Ronda 1223 caliber is unique and strictly mechanical: the top crown is dedicated to winding the mainspring and setting the time. The bottom crown operates the alarm function exclusively: rotating it counter-clockwise sets the red alarm hand, and winding it charges the separate alarm spring. Please note that this specific design lacks a pull-out selector to deactivate the alarm—once the spring is wound, it will naturally ring when the hour hand meets the alarm index 

Dial:
o Untouched blue

Bracelet Material:
o New 18mm dark blue leather with generic chromed buckle

Condition:
A nice vintage alarm watch in working condition…
