Heuer 989.113L Night Diver
Heuer 989.113L Night Diver, Pewter PVD, Full lume dial. c1985
This is a very late Heuer diver, noted by the ‘L’ at the end of the model number. These also featured an elaborate signed case back, 1000 on the dial and a signed crown. It’s unbelievably rare (never seen another, anywhere), as it was so late in the Heuer range, just before the TAG takeover.
There are very similar models that appear the same, but have a different model code. The ‘989’ code was originally believed by Heuer collectors to be only seen on the newer TAG versions, until I turned this one up, and a Heuer catalogue page was later discovered with it in. There doesn’t seem to be a good reason why the code structure changed, usually the codes follow on from the older models. One reason could be that the case is slightly thinner than the earlier example, but that happened to other 1000 divers and the code stayed the same.
