Object description

Case and Dial Configuration

The watch is housed in a reversible titanium case, which enables the user to display one of two sides. Each side functions as a distinct dial for managing two independent time zones. The mechanism facilitates the rotation of the main watch head within the integrated lugs.

The primary dial presents a classic layout, incorporating a guilloché texture. This side is finished with Arabic numerals and signature pomme-style hands. In contrast, the secondary dial utilizes a modern, open-work aesthetic. It features a prominent deltoid-shaped hour hand located above the balance wheel and a peripheral track for minute display.

Evidence for this section
  • “ویژگی برجسته این ساعت، برخورداری از یک قاب چرخان و برگشت‌پذیر (Reversible) از جنس تیتانیوم است که دو صفحه کاملاً متمایز را در دو سوی خود جای داده است.”
  • “صفحه نخست ظاهری کلاسیک و سنتی دارد که با الگوی گیوشه (guilloché)، عقربه‌های موسوم به pomme و اعداد عربی اختصاصی برند De Bethune آراسته شده است.”
  • “در سمت دیگر، صفحه دوم با هویتی کاملاً مدرن و پیشرو خودنمایی می‌کند؛ این صفحه دارای یک عقربه ساعت‌شمار دلتوئید (مثلثی) در بالای بالانس، عقربه دقیقه‌شمار محیطی (peripheral)”

Movement and Mechanics

The watch is powered by the manual-winding caliber DB2517. This movement is reported to consist of 394 individual parts, engineered to manage the requirements of the dual-display system. It provides the necessary energy to support the distinct timekeeping functions displayed on both sides of the reversible case.

A key mechanical feature of the caliber is the central deadbeat seconds escapement. The movement is further accented by decorative techniques, including a stepped black-polished deltoid spring barrel bridge visible on the contemporary side of the watch.

  • “نیروی محرکه هر دو نمای این ساعت از موتور مکانیکی کوکی کالیبر DB2517 تأمین می‌شود که طبق توضیحات منبع از ۳۹۴ قطعه تشکیل شده است.”
  • “پل مخزن فنر دلتوئید با پرداخت پولیش سیاه پله‌ای (stepped black polish) و مکانیزم سنترال ددبیت سکندز (deadbeat seconds escapement یا ثانیه‌شمار پرشی) است.”

Background and Production

This model was created to mark the twentieth anniversary of the De Bethune brand. Due to its status as a commemorative piece, production was strictly limited to twenty examples.

The piece is presented on a black leather strap. While the source details the technical specifications of the movement and the dual-face architecture, it notes that no specific information regarding the service history or the current functional performance of the watch is available.
