The full size, TAG Heuer Link Chronometer model was the one to have if you could afford it.  Model reference WT5110-BA0550.


While we have the Chronometer Certificate (which matches the serial number on the case back), booklet and instruction book we do not have the original sales card which would show the date of sale.  The production stamp for the booklets are both from 2002, so we know the watch couldn’t have been made before then.  The Link model ran from 1999 to 2012, but the WT designation models were updated in 2004.


In case you were not aware, a watch can only be called a Chronometer if it is independently tested to meet accuracy of between +6/-4 seconds per day for a mechanical watch.  The testing is carried out by the Swiss Official Chronometers Control, often abbreviated to COSC.  To achieve this you have to use a very good movement, and this watch is fitted with a ETA 21 jewel automatic movement, branded for TAG Heuer.  Cosmetically the watch is in very good shape, and there are just a few marks to the matte finish on the case and bracelet,  The sapphire crystal is perfect, and the dial and hands are clean and correct.  The rotating bezel rotates in one direction only, as it should.    The bracelet is quite long and our sister website,, may have extra links if required.  The bracelet has been cleaned in our ultrasonic bath.

This watch will be supplied with the original presentation boxes, papers and our Certificate of Authenticity.  The boxes are showing wear and the zip handle is missing on the inner box, but the zip still functions without it.

From 1st September 2021 we will be planting a tree for every watch we sell, working with the International Tree Foundation (Est 1922) to make this business positive on carbon.  By buying anything pre owned you are effectively reusing what already exists, but this takes it further and makes us feel good.
