The external rotating bezel is paired with an unsigned crown sheltered by integrated crown guards. It is fitted with a black rubber strap in a tropical style, secured by a stainless steel pin buckle. , though no specific information regarding its movement caliber or maintenance history is provided by the source.

Object description

Design and Case Construction

The timepiece features a 42mm stainless steel case identified by the source as a "Monnin" construction. This design incorporates a rotating diver's bezel and integrated crown guards to protect the unsigned winding crown. The use of this specific case style is associated with Heuer's transition into the production of tool watches for underwater use, reflecting the outsourcing strategy employed by the brand during this phase.

The aesthetic of the watch is defined by a matte black dial, which features tritium-based indices displaying uniform patina. The hour and minute hands are designed in a cathedral style, featuring matching aged luminous material. A date aperture is located at the 3 o'clock position on the dial. The overall presentation is completed by a black rubber strap featuring a tropical-style perforation pattern and a stainless steel pin buckle.

Evidence for this section
  • “بدنه این ساعت یک قاب قراردادی ۴۲ میلی‌متری مشهور به «مونین» (Monnin) است”
  • “صفحه ساعت به رنگ مشکی مات با نشانگرهای تریتیومی دارای پتینه یکدست و عقربه‌های سبک کاتدرال (Cathedral)”

Provenance and Historical Context

Introduced in 1979, the reference 844-1 represents a departure from Heuer’s traditional focus on racing chronographs. As the brand entered the diver's watch market, it relied on external suppliers for key components, including the case and movement, as it lacked internal expertise in specialized maritime timekeeping.

This model is recognized as one of the earlier attempts by the brand to establish a presence in the professional diver's watch category. The inclusion of the word "Professionel" on the dial is noted by the source as an indicator of its French manufacture, highlighting the collaborative production methods employed during this transitional period in the company's history.

Evidence for this section
  • “از نخستین تلاش‌های این برند برای ورود به بازار ساعت‌های ابزاری زیر آب به شمار می‌رود”
  • “هُوِر در ابتدای ورود به عرصه ساعت‌های غواصی فاقد تجربه تخصصی در این بخش بود و به همین دلیل قاب‌ها و موتورهای مورد نیاز را برون‌سپاری کرد”
  • “عبارت «Professionel» بر روی صفحه، طبق توضیحات به خاستگاه ساخت فرانسه آن اشاره دارد”

Condition and Technical Status

The source reports that the tritium-based hour markers and the cathedral hands display a natural and consistent patina, indicating a degree of preservation in its original aesthetic state. The watch is currently paired with a black tropical-style rubber strap and a stainless steel pin buckle.

While the physical appearance of the timepiece is described as preserved, there is no information available regarding the movement caliber utilized inside the case. Furthermore, the source explicitly states that there is no record of the watch's technical service history, leaving its internal mechanical condition unverified.

Evidence for this section
  • “نشانگرهای ساعت و عقربه‌های کاتدرال دارای پتینه طبیعی و یکنواخت بوده و وضعیت کلی قطعه حفظ شده است”
  • “اطلاعاتی پیرامون تاریخچه سرویس فنی پیشین در گزارش فروشنده ثبت نشده است”
  • “جزئیات دقیق کالیبر موتور ساعت در منبع ذکر نشده است”
