Glycine Airman SST "Pumpkin" Wristwatch

Partially verified

This 1969 Glycine Airman SST, nicknamed "Pumpkin", is a stainless steel 24-hour pilot's watch featuring a 41.5mm tonneau-shaped case. Designed for the jet age, it incorporates an internal orange 24-hour rotating bezel. The dial is divided into a gray AM half and a black PM half, with a date window positioned at 6 o'clock. Tritium luminescent markers show a creamy yellow patina. It is powered by an automatic mechanical movement that has been recently serviced. The watch is paired with its original Glycine SST flat-link steel bracelet. The case back displays an engraving of a supersonic transport aircraft. This specific timepiece is presented as a functional vintage example of the SST (SuperSonic Transport) model introduced in 1967.

Object description

Case and Dial

The watch is housed in a 41.5mm tonneau-shaped stainless steel case that retains its original factory dimensions and bevelling. A distinctive feature is the internal rotating 24-hour bezel finished in a bright orange color, which serves as the origin of its 'Pumpkin' nickname.

The dial uses a 24-hour display architecture, bifurcated into a gray section for AM and a black section for PM hours. The hour markers consist of tritium-based luminescence, which has aged to a creamy yellow patina. A date window is located at the 6 o'clock position.

Movement and Functionality

The timepiece is driven by an automatic mechanical movement. The source reports that the movement has been recently serviced, confirming it provides functional timekeeping accuracy.

Functional elements include the internal rotating bezel, which allows for secondary time zone tracking, and the 24-hour hand configuration designed to distinguish day from night during long-haul flight operations.

Historical Context and Condition

The Glycine Airman SST, with SST denoting SuperSonic Transport, was launched in 1967. The case back features an original factory engraving of an SST aircraft.

The exterior of the case shows signs of wear consistent with previous use. The original flat-link stainless steel bracelet is also noted to have minor stretching and usage marks, yet it remains in good condition. No original packaging or documentation accompanies this watch.

Evidence for this section
  • “نسخه SST (مخفف SuperSonic Transport) در سال ۱۹۶۷ معرفی شد و تحت تأثیر توسعه پروازهای مافوق صوت نظیر کنکورد و طرح بوئینگ ۲۷۰۷ شکل گرفت”
  • “بر پشت قاب تصویر هواپیمای مافوق صوت SST و حکاکی‌های اصلی کارخانه نقش بسته است”

  • “همراه ساعت جعبه یا مدارک ارائه‌نشده ذکر شده است”

Open research questions

  • Can the specific year of production be confirmed through an archived serial number list for the SST model?
  • What specific professional aviation standards or patents supported the original 24-hour dial design for the Airman line?
