It's a highly collectable watch because it runs on the Tissots cal. 2020 "the hummer", which is Tissots eta based movement which was made using the patented tuning fork technology, leased from Bulova. (the most accurate and reliable in its time). The main feature of the 2020 calibre is, that gentle sweep of the second hand; the watch doesn't tick - it just gently sweeps making the famed humming sound(it is very quiet in this model comparing to the original bulova models running on the caliber 214).The dial is in a mint condition and simply hypnotizing; makes you want to check the time way too often than its necessary. There is some minor scratches on the case and some on the crystal, but nothing very visible. The crown is a bit worn but it is not extremely noticeable.
(all can be seen on the pictures). The case of the watch together with its crown was completely renovated by a talented professional (as you can see by the final result). The watch was revised by a watchmaker in September and keeps the time up to around 10-30 seconds per day in case of these watches it varies widely based on the temperature etc.The watch comes with a great looking Italian leather strap. Crown: 39 ø x 42mm high and around 11mm thick. My wrist is around 17cm for the reference. Pictures are a part of the description.
