|Comment||Breitling Chronoslide Type 1677 device with the central “totaliser” hand rather than
the separate small dial (Type 1577) are far rarer, and definitely more unusual.
The larger central dial makes the stop watch function far easier and quicker to read,
however there is no difference in accuracy between the rotating bezel slide rule on
this and the other Breitling Chronoslide Model.
