АТМОС отстают 5 минут
 

Отстают на пять минут в сутки, может у кого есть опыт по выставлению точности в этих часах?
Торсион укоротить некуда, маятник подвешен впритык.
Спасибо.

Доброе утро, Дмитрий!

Вот, может Вам помочь, надеюсь.

"Timing Adjustments

Because of various scientific reasons, mostly different room temperature ranges, you can expect the Atmos to be off by as much as 30 seconds per day after a move or after service. So please be aware that you will have to adjust the timing for your "area". Most every Atmos has a speed adjustment located at the top of clock. This is a straight lever, which can be moved either left or right. Moving the lever to the left side stands for Slow or Retard and the right side stands for Fast or Advance. The scale has lines on it each representing ten (10) seconds per day. So the maximum you can adjust the clock either fast or slow is fifty (50) seconds per day.

On the newest models (caliber # 540 and the anniversary model) there is a sixty (60) second adjustable amount which is indicated by a plus (+) or a minus (-). The plus (+) would be to make the clock run faster.

Timing should be done at roughly the same time of day and the time recorded once you observe the "tick" or movement of the minute hand. Be sure to use the same timepiece each time when comparing the accuracy of your Atmos. Record the exact time the minute hand moved its 30-second tick and the direction that the balance was moving. Then at the same time the next day or next week or whatever, record the time using the same parameters and adjust according.

Remember that the clock ticks once every 30 seconds and the adjustment scale is broken down to 10 second per DAY intervals. Don't get too obsessive because an Atmos will never keep perfect time but it should be accurate to within a minute a month and 30 seconds a month can be expected.

On models made prior to 1949 - 1951, which are the Atmos II's, LeCoultre's first true production run, there is an adjustment knob located at the rear in the upper right side as you face the front of the clock. Some have the adjustment knob located in the front upper right. This knob also has "F"ast and "S"low indicators and you would turn the knob in the appropriate direction. From what I have been informed, each full turn represents 10 seconds per day but you'll have to experiment."

Спасибо, Душан.
Это лишь подтверждает что часам требуется более глубокое вмешательство чем просто регулировка. В приведённом Вами тексте указывается максимальная корректировка в 50 секунд, а они отстают на 300 секунд.
К тому-же регулировка установлена до конца на +.
С уважением, Дмитрий.

Да, совершенно верно.

На нижней стороны баланса, внутри, есть 2 винта, на которые крепятся регулировочные тяжести. Нужно заменить или сделать легче тяжести. Если сделать легче, то нужно сохранить уравновешенность баланса.

Они наборные, для начала попробую снять по одному сегменту, а там видно будет.
Думал может есть какая хитрость, видно придётся доставать механизм.
Спасибо, напишу когда получится
