With the full gold, fish scale bracelet this rare Eterna-Matic 3000 was the world’s flattest self-winding calendar watch with centre seconds.  Model reference 746T.


From the supplied paperwork, which matches the serial number on the case back, we can accurately date this watch to being sold on Valentines day, 1966.


This was the flagship of the entire Eterna-Matic range, and will have been an expensive watch.  The reason you don’t see many is that the price of gold more than quadrupled in the next fifteen years, so the temptation to sell the watch, our even just the bracelet, must have been huge.  The owner of this watch resisted the thought of making money, and kept the watch together.  In fact they did more than that – they kept the paperwork, and a couple of spare 18k gold links.  The dial doesn’t say Eterna-Matic 3000 and is silver rather than gold like the one we have found in a sales catalogue of the day – there may have been variations, or it may be a replacement dial.  The movement is Eterna’s 1466U – a super slim 21 jewel movement with quick set date (operated by pulling the crown).  It was later developed into the ETA 2892, which can be found as a base ebauche in many high end watches even today.  The screw down case back hides the movement, but again is solid gold.  The bracelet is integrated to the case and can be taken off for cleaning or to swap the look if wanted.  The fishscale pattern is appealing and there is no twisting like affect most integrated gold bracelets.  The clasp has a logo we don’t recognise but is stamped 750 Eterna 2344 inside.
