Vintage 1970s Seiko Bell-Matic — Automatic Ref. 4006-6100,caliber 17-jewels Alarm Complication, Blue Dial Japan made Men’s watch (Used)

Pre-owned Price 1380 AED

**Movement:** Seiko caliber 4006, automatic with mechanical alarm function, 17 jewels — the famous “Bell-Matic,” one of the few automatic watches ever produced with a built-in alarm, set and activated via the second crown.

**Case & Dial:** Stainless steel case with a striking deep blue gradient dial that shifts tone across its surface. Applied silver baton markers with luminous accents and a two-tone (mint/white) minute track around the perimeter. “SEIKO” signed at 12, “BELL-MATIC 17 JEWELS” text below center. Day/date window at 3 o’clock displaying “WED 25.” Second crown at 4 o’clock position for alarm setting, in addition to the standard crown. Case reference “JAPAN 4006-6100T” printed on the dial.

**Case Back:** Solid stainless steel case back engraved “SEIKO WATER RESISTANT,” reference 743577, “STAINLESS STEEL 4006-6100,” and “JAPAN A” — confirming authenticity and matching the dial reference.

**Bracelet:** Stainless steel bracelet, in good condition with light age-appropriate wear.

**Condition:** Pre-owned, running. Dial retains its distinctive blue gradient finish with honest vintage character; case shows expected handling marks and light surface scuffing on the case back, typical of a well-used vintage piece.

**Collector Notes:** The Bell-Matic is a genuine mechanical curiosity — one of very few automatic alarm watches ever mass-produced, using the winding rotor’s energy to power both timekeeping and the alarm function. A must-have conversation piece for any serious Seiko or complication collector, offering real mechanical novelty beyond a standard time-and-date automatic.
