Master Moon pairs a full-calendar chronograph with the warmth of 18k rose gold, housing Mission Moon's elaborate silver dial behind sapphire. Its dial bears the red ‑ white ‑ blue TWC crest and Breguet ‑ style blued ‑ steel hands, paying tribute to American craft. Inside beats a Swiss ETA/Valjoux 7751 calibre rebuilt by Jochen Benzinger — skeletonized, engraved, and gold ‑ plated to reveal its lunar phases and calendar works. This heirloom edition stands at the crossroads of Baltimore artistry and German engraving, capturing Towson’s most complicated complication set with materials and finish worthy of 19th ‑ century chronometer makers. Limited and long retired, it remains a history lesson for the wrist.
