Selling my Brellum Duobox Triple Calendar Moonphase Chronometer — an incredibly rare independent Swiss piece with exceptional finishing and complications rarely found at this price point.

• Limited edition: only 46 pieces worldwide
• COSC-certified chronometer (-4/+6 sec/day)
• Brellum BR-751 automatic movement (Valjoux 7751 base)
• Triple calendar + moonphase + 12-hour chronograph
• 41.8mm stainless steel case
• Double box sapphire crystals front & back
• 100m water resistance
• Beautifully decorated movement with Geneva stripes, blued screws & engraved rotor
• Black alligator strap with deployant clasp

Brellum produces only 299 watches per year across all models, making these extremely hard to find. The attention to detail, finishing, and overall quality genuinely compete with watches from brands costing significantly more.

A perfect piece for collectors who appreciate independent Swiss watchmaking and rare complications.
