A mechanical full stop

This very late Special still feels like a complete idea. Its sharply drawn steel case, frosted dial and original bracelet bring together quite different kinds of surface without losing their common discipline. My example dates from August 1974.

The dial is extraordinary in sunlight. Its fine, diamond-dust texture gives the polished markers a crisp, sparkling ground. There are no black accents to pin them down: light itself has to describe the shapes, recalling something of the earlier Grand Seiko dials within a much later composition.

The bracelet is part of it

The second and fourth rows of bracelet links are polished, while the surrounding surfaces are brushed. That alternating treatment matters to the way the whole object reads. It extends the contrast of the watch across the wrist without turning the bracelet into an unrelated accessory.

This watch arrived with the signs of a long working life. Lapinist subsequently restored both the case and that complicated bracelet. Recovering their precise edges and contrasting finishes made the relationship between the parts legible again. The pleasure lies as much in those junctions as in the luminous dial.

Two steel Specials

I have photographed this late 8040 beside the June 1971 6156-8010. The earlier watch concentrates much of its animation in the cut crystal and delicate dial furniture. Here the frosted dial and striped bracelet take on more of that work. It is another way of arranging light within the same Special family.
