De Bethune DB28 Kind of Blue Milky Way

Partially verified

This De Bethune DB28 Kind of Blue Milky Way is a wristwatch identified as the first of an edition of ten. The timepiece is notable for its heat-blued titanium construction, applying the treatment to both the case and the dial. The dial features gold-engraved motifs representing the center of the Milky Way galaxy. The movement is the manual-winding caliber DB 2115, which consists of 299 components and provides a six-day power reserve. This energy is managed by two self-regulating spring barrels, visible at the periphery of the dial. Additional technical components include a balance wheel constructed from titanium and white gold, and a spherical moon phase indicator made from palladium positioned at the six o'clock mark. The case design incorporates the signature floating lugs associated with the De Bethune DB28 series. The watch is worn on a black strap.

Object description

Case and Dial Construction

The De Bethune DB28 Kind of Blue Milky Way is constructed entirely from heat-blued titanium, a material treatment that gives the case and dial its characteristic blue coloration. This specific model is identified as the first of a limited series of ten units worldwide.

The dial layout includes a gold-engraved design representing the Milky Way galaxy. Integrated into the dial architecture are the spherical palladium moon phase display, a power reserve indicator, and the balance wheel assembly, which is crafted from titanium and white gold.

Evidence for this section
  • “نخستین مدلی است که تمام بدنه و صفحه آن از تیتانیوم حرارت‌دیده به رنگ آبی (heat-blued titanium) ساخته شده است”
  • “صفحه ساعت دارای نقوش برجسته و حکاکی‌شده با طلا است که نمایانگر مرکز کهکشان راه شیری است”
  • “نمایشگر فاز ماه کروی از جنس پالادیوم و نشانگر ذخیره انرژی جلب توجه می‌کنند”

Movement and Technical Features

The watch is powered by the mechanical caliber DB 2115, a movement comprising 299 individual components. The caliber is designed to provide a six-day power reserve, supported by two self-regulating mainspring barrels. These barrels are positioned for visibility at the edge of the dial.

The DB28 architecture is distinguished by the use of floating lugs, which allow the case to conform to the wearer's wrist. The movement also features a balance wheel made from a combination of titanium and white gold.

Evidence for this section
  • “کالیبر مکانیکی DB 2115 با ۲۹۹ قطعه مجزا طراحی شده است”
  • “از طریق دو مخزن فنر کوک خودتنظیم‌شونده که در لبه صفحه قابل مشاهده هستند، ذخیره انرژی چشمگیر ۶ روزه را فراهم می‌آورد”
  • “مدل DB28 به واسطه ساختار خاص قاب و پایه‌های متحرک شناور (floating lugs) جایگاه ویژه‌ای در ساعت‌سازی معاصر دارد”
