A581 movement and Age confirmation

A581 movement.

 

Access Resolution A581 movement also spread over the "movement of the balance wheel 581 rivets must be placed," the statement said that nearly led to the future of this modified A581 except the case a lot of reasons, in fact, late in 1964, Shanghai Watch Factory has full range of watches Use light balance, so from a few parts of the A581 using the inventory, the basic plant in the table 581 movement in the late 1964 using the "light wheel." A581 movement in the Den will be the movement for "no shock" movement and whether the primary splint with fixed screw holes as the standard. All are with the A581 movement control functions and use the five "ears" of the movement to secure the clamping ring.

 

 

Age confirmation.

 

The watch factory products to consumers all have a two-year commitment period of warranty, so the A581 in the 61 years since the end of the movement in the balance wheel movement have begun to fight on the deck of the date of manufacture and the movement 61 years ago not to play number, date number, arranged for the four-digit number plus a letter, the most representative of the previous two figures, the year of the last two digits represent the month, making the first letter on behalf of several groups of products the same day; such as "6105A" represents 61 years in May the first batch of products. Now I have found the first movement with the movement number as 61 years in March of the products.
