It has the iconic ESA chronometer electronic tuning fork movement, known as the hummer from its distinctive sound, and has been brought up to spec with the addition of the new, new old stock (NOS), and replacement parts listed below. Tissot Tissonic Electronic tuning fork watch. Tissot 2020 (ESA 9164) with serial no. 19518605 from 1976 year of manufacture, with quickset day and date function. Gold plated Tissot type 47613 with stainless steel screw back cover.
36mm across not including the crown. Beautiful original Tissot gold sunburst effect dial with Tissot logo and stylized sinusoidal design (to represent the F300 frequency waveform). Gold/white hour markers to perfectly match the original hr/min hands and gold sweep seconds hand. Sternkreuz armoured ring crystal (ATGR-311).
Leather strap, with matching Tissot signed gold tone buckle (T640), and spring bars. Correctly sized 344 button cell battery.Only the best Moebius oils and grease have been used and applied correctly during the comprehensive service (types 9010, 9020, 8201 Moly, 8200, 8300, silicone). Light hand polish of case to reduce the appearance of any blemishes, and hand polish of the case back.
Extended test accuracy (on bench, dial up) is excellent, within a couple of seconds average per day. Other: As expected of a vintage watch there are some signs of age/patina/marks etc, as photographed.
Internally there is some discolouration around the battery well from a previous leak, but this is only cosmetic. The crown has plating wear to its top surface. The watch also had an Omega signed crystal when it came to me, but it was scratched so a brand new crystal has been fitted.All relevant components have been demagnetized. As with most vintage watches it no longer has its original box or paperwork.
Note that my vintage watches have no guarantee of being water resistant/proof, and you should assume they are not. The crown is pulled out to the mid stage to quickset the day and date; it is then pulled out a stage further in order to set the hands (or store the watch as this is also the power Off position). It is drawing 9/10 micro amps full-load current at 1.35/1.55V, and has been tested to work correctly over the 1.05 to 1.65V voltage range. All electrical resistance measurements of coils and transistor are satisfactory. Without revealing details this may also include the following.
Sorry for any inconvenience in having to put these security measures in place. Guarantees or warranties given after dispatch. The images form the primary description of the item; please study them carefully as they take precedence over all written information. In Addition, for Watches and Clocks.
This finite ability should not be unduly overestimated, and certainly should not be compared to the expectations of that of modern-day timepieces. I consider a tolerance of +/-3 minutes per day accuracy to be good, and +/-1 min per day to be excellent, and most of my wristwatches are even better than this.
This should be performed by a qualified and competent person at the buyers expense. In addition, unless specifically described as fully serviced/cleaned, it is to be assumed that all timepieces will require some level of service/repair from the time of their receipt, and at the buyers expense. As with any mechanical device, timepiece components can fail at any time, and often without warning e. The watches I sell have no guarantee of being waterproof regardless of their design or wording, and you should assume and care for them as though they are not.
