Longines Master Collection Chronograph Automatic, reference L26734, a heavily modified Valjoux 7751. 

This watch was made in the early 2000s to early 2010s. From a local estate.

All functions work as they should. The chronograph function is fully operational — the chronograph starts, stops, and resets correctly at12:00. 

See the photos of the cone for bracelet size.

Service Disclosure: This watch is currently running and fully functional, but according to my local watchmaker it is showing low amplitude (between 203 and 225). My local watchmaker, John Hood, Martinez and Hood, Watches to Jewelry, in Austin, Texas, believes the movement is dry and just needs servicing. No other issues were detected. Servicing should address the low amplitude and will allow a watchmaker to attend to any other issues or maintenance the movement may require. I am selling the watch with the expectation that the buyer will have it serviced before relying on it for regular use.

On a full manual wind without any wrist time, the watch ran for nearly 51 hours. 

• After 20 hours, -4 seconds
• After 33 hours, -7 seconds
• After 45 hours, -30 seconds

Note that calendar corrections should be avoided during the period 8 p.m. to 2 a.m. because the movement may already be engaging the date/day change mechanism.

Similarly, only advance the day when the watch is NOT running.

Please review all photos carefully, as they are part of the description and show the actual watch being offered.

Note that I am adding a $30 handling fee to cover the cost of insurance.
