1972 Seiko 4006-6031 Automatic “Bell-Matic” 17j

$0.00

The first Bell-Matics were released in November of 1966, and over the next 12 years a wide variety of styles and color combinations would guarantee that those looking for a robust wrist alarm with undeniable presence could find exactly that. Seiko’s 4005 and 4006 calibre movements were available in 17j export and 27j domestic market versions (there’s even short lived 21j variant), both of which offer incredible reliability decades after they were first produced. From classic dress styles to colorful casuals, there’s a “Bell” to suit any collection. This 6031 from July of ‘72 is a casual classic with broad appeal and a versatile layout. The 39mm cushion case has soft contours, and a slimmer profile than is typical of most Bell references. The dial is a deep navy blue with a subtle sunburst beneath a glossy lacquer finish. It’s set with polished applied baguette markers with black enamel tips and stepped luminous plots. Polished and beveled batons track and hours and minutes, and a long slender sweep counts the seconds. Framing the dial is a wide inner bezel with a bright red cutaway cursor that reveals the dropped minute chapter beneath for precision setting of the alarm. It’s unpolished and completely original aside from a replacement crystal, and post service is keeping near perfect time. The bell has a bright crisp tone, and accurate alignment. The date can be quickset by pressing the alarm toggle pusher, and the day is semi-quickset via the crown. We’ve paired it with a soft olive suede that gives this “ringer” a comfortable fit and finish that’s suitable for any setting.
