Descriptions :
BREITLING Gold Filled "NAVITIMER" Manual Wind 3-Reg. Chronograph with Box (No Paper). Ref.1639. Circa 1980s/90s.
Dial :
Signed and original black complicated dial appears to be in excellent / mint condition. The only flaw that I can spot on this part has been the measure rule of the rotating bezel which looks to me that someone was trying to repair the crystal and the glue used got onto the bezel. (I personally think this can easily be fixed by replacing the measure rule & this shall not cost much and can be easily done by opening the snap on rotating bezel. Otherwise the dial itself is very good in condition.
Case :
Signed and original GF case appears to be in fair / good condition with very minor wear shown on case. Snap type back cover has a few small open marks appears mainly on the edge of the back cover which can easily be removed by polish. Plastic protection sticker still attached on the back cover center. Case reference : "81800". Signed original GF crown has been slightly worn with tiny area of the GF worn out. Signed and original black leather strap & buckle. Sapphire crystal is in MINT condition with no scratch.

Size Measured = 42mm without lugs & crown.

Movement :
Signed and original manual wind movement appear to be in excellent running condition which I have not personally opened for inspection as to make sure it's waterproof ability.
Remarks :
Watch overall in reasonably good condition. Good for daily use. Some minor extra work will make it look excellent again. I personally have a few NAVITIMERs and I really think that are reliable watch to wear.
