Over the past 2 months or so I’ve covered my 8100A chronograph collection, so time now to move on to an 8110A model. This one has no model number, so (as I suggested yesterday) it’s likely that it was originally made for the Japanese Domestic Market only. The case design is the same as the much better known model 67-9011 – the ‘bullhead’ – with its apparent stainless steel case (actually a nickel alloy), but this one has a black coated light alloy case and polished steel bezel. And it sports a very different colour palette on the dial – the main colour is green, with a black minute/second track and black sub-dials with multi-colour highlights. It’s finished off with orange centred hands, orange chronograph hands, orange highlighted hour markers and black date and day wheels. Despite the various colours it presents as a harmonious design in my opinion. The 8110A hand winds, has quick-set day and date (the stop/reset chronograph button moves the day forward on all 8110 and 8100 movements) and of course if has ‘fly-back’ capability. Mine is from December 1973:

Here’s this model in a 1974 Japanese catalogue – as you can see there is no model number in the form of 67-xxxx, but there is a different type of reference number – for this one it is 1552-21. It’s also interesting to see the original strap used on this model, alongside the more familiar bracelet on the 67-9011 seen here:
