FOR PARTS/REPAIR – The ETA 2788 automatic movement does not run. Both the day and date wheels roll over as they should. At a minimum a complete overhaul is required. This seldom seen vintage 1970’s Tressa, which came from the estate of its original owner, has a silver satin “SWISS MADE” signed dial that under the damaged crystal appears to be in near pristine condition. Majority, if not all, of the imperfections seen are on the outside and underbelly of the crystal. The black lume, which I suspect is original, does not glow when exposed to bright light. In my humble opinion the vibrant powder blue seconds hand complements the dial and lume beautifully. The all stainless steel case shows significant wear with no visible signs of oxidation. The outer edge of the case back is stamped “WATERPROOF INCABLOC AUTOMATIC STAINLESS STEEL SWISS MADE” with “TRESSA” followed by “SWISS” stamped in the center. The crystal needs to be replaced. The 25 jewels Swiss “TRESSA” stamped ETA 2788 automatic movement with quickset date function does not run. The quickset date function works flawlessly by pulling out the crown to the first position and then turning it clockwise until the desired date has been reached. This movement does not have a quickset day function. The signed, non-screwdown crown winds with friction. This watch measures approximately 35 mm excluding the crown, approximately 36.5 mm including the crown and approximately 19 mm between the lugs. Case thickness, measured from the bottom of the case back to the top of the mid-case, is approximately 9 mm. Including the crystal thickness measures approximately 11 mm. As such there are no warranties, express or implied, attached with the sale of this watch. Vintage means old and while my personal belief is that old-school means better quality and workmanship, things can and do go wrong from time to time. For this watch that time is now. Any servicing costs going forward are your responsibility. And please study the 17 high magnification pictures carefully, which were taken in natural light and from various angles, as they are part of the description and serve as an accurate representation of the condition of this watch.

Until recently the movement was keeping accurate time. While the seconds hand continues to run strong, albeit fast, the minute hand now has a tendency to start and stop, moving inconsistently on its own. Sometimes the watch runs as it should, although a bit fast, during a full power reserve cycle while other times the minute hand gets stuck repeatedly. When this happens I’ve noticed that after several minutes the minute hand tends to re-engage and start moving again, sometimes without further issue while other times the process repeats itself until the kink is worked out. Considering that this watch appears to be untouched and having never been serviced, a full overhaul is needed. This classy vintage Tressa diver appears to be untouched and has a pristine blue satin “T SWISS MADE T” signed dial that is in pristine condition, free of any visibly noticeable scratches, tool marks, chipping or defects. The original tritium on the dial and hands remains fully intact, matches perfectly and no longer glows after being exposed to bright light. The patina has aged beautifully to a deep golden brown sugar hue. In my humble opinion the dial and patina couldn’t be more pleasing. The silver and powder blue world time bezel, which rotates bidirectionally, looks great. The solid all stainless steel case shows age-related wear and some minor dings. The outer edge of the case back is stamped “SWISS MADE WATERPROOF INCABLOC STAINLESS STEEL UNBREAKABLE MAINSPRING” with “AUTOMATIC” stamped in the center. The crystal shows scratching. The 25 jewels (dial says 17 but movement is stamped 25) “SWISS” and “TRESSA” stamped Felsa 4462 automatic movement with quickset date function is in wonderful condition and until recently was keeping accurate time. While the seconds hand continues to run strong, albeit fast, the minute hand has recently started becoming stubborn, starting and stopping inconsistently. The quickset date function works flawlessly by manually rolling over a new date then then repeatedly moving the hour hand between the 21 and 24 hour marks until the desired date has been reached. After winding the sharply threaded, non-screwdown crown 39 full revolutions the movement had a strong power reserve period of approximately 37 hours. Given that this watch is likely more than 45 years old, that the minute hand has been getting stuck and considering that the movement appears to have never been serviced (there are no watchmaker service markings on the inside of the case back), a complete overhaul is needed. This watch measures approximately 37 mm excluding the crown, approximately 40 mm including the crown and approximately 19 mm between the lugs. Case thickness, measured from the bottom of the case back to the top of the bezel, is approximately 8.5 mm. Including the crystal thickness measures approximately 10 mm. This watch comes on a brand new powder blue Nato strap with matte stainless steel buckle that matches the blue on the bezel nicely and complements the dial beautifully. Given the vintage nature of this watch, that the minute hand has been getting stuck and considering that the movement appears to have never been serviced, a complete overhaul is needed. As such there are no warranties, express or implied, attached with the sale of this watch. Vintage means old and while my personal belief is that old-school means better quality and workmanship, things can and do go wrong from time to time. For this watch that time is now.
