As a result I’ve only observed the power reserve lasting for a few hours at a time despite winding the crown 39 full revolutions. A skilled watchmaker can source and install these missing parts. This rarely seen vintage Louis diver has oodles of character and is an interesting project. The “Ra SWISS MADE Ra” and “1.5 UC” signed dial shows age related wear. The original lume on the dial and hands emits a short-lived glow after being exposed to bright light. While the lume on the dial has developed a pistachio hue the hands have aged to a warm buttermilk patina. The black bezel, which rotates smoothly bidirectionally, looks great with a lume pip that has aged gracefully to a golden butterscotch hue. The all stainless steel case is in excellent condition, showing minor wear and free of any visibly significant dents. The outer edge of the case back is stamped “SUBMARINE CASE AUTOMATIC INCABLOC ALL STAINLESS STEEL SWISS” with “LOUIS” followed by “800 FEET – 20 ATM, “”SUPERWATERPROOF” and 26746. The crystal is in good shape but does have some dust/debris on its underbelly. Additionally some dust/debris has landed on the dial. The unadjusted AS 1712 automatic movement with quickset date function is clean, keeps accurate time and the quickset date function works flawlessly. The quickset date function works by rolling over a new date and then moving the hour hand repeatedly between the 20 and 24 hour marks until the desired date has been reached. While the movement keeps accurate time, it’s missing its oscillating weight and the part that the oscillating weight sits on. As a result and despite winding the crown an average of 39 full revolutions on several occasions, the power reserve only lasts a few hours at a time. Given that this watch is approximately 45 years old, that the movement is missing its oscillating weight and the part it sits on and considering that the movement has an unknown service history, a complete overhaul is needed. This watch measures approximately 37 mm excluding the crown, approximately 40 mm including the crown and approximately 18 mm between the lugs. Case thickness, measured from the bottom of the case back to the top of the bezel, is approximately 10 mm. Including the crystal thickness measures approximately 13 mm. As mentioned above, given the vintage nature of this watch, that the movement is missing its oscillating weight and the part that the oscillating weight sits on and given its unknown service history, a complete overhaul is recommended. 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 12 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.
