A notable mention is the Calypsomatic reference 3552. While many people have never heard of this reference the community found that it does exist and is quite confusing to date. I chose not to go deep into this reference because it does not have a gilt dial. The print is silver with the early style large logo and "Titus", it can have a lollipop or mercedes hand, a non drilled lug-hole case, a 7085 big crown and a 3552 engraved case-back. It appears to share parts within the range of the early 7085 and 7986. Now this could simply be a service parts watch but that wouldn't explain the unique numbered case-back unless Titus issued a new case-back from service. Or it could just be a reference Titus simply never intended to produce but just wanted to assembles parts they had left over and create a quick reference to cash out. It certainly feels incomplete and unoriginal to just mash together parts. Something worth noting is that in the 70's Titus was struggling as a brand and was later acquired by a Hong Kong based company. Maybe this is Asia's version of a last ditch effort Calysomatic? I only have seen a few of these over the years so it remains a mystery.
