Specialized Compatibility： Designed for polygonal (12‑sided or 15‑sided) screw‑down case backs on Breitling watches; also works with other brands sharing the same case back geometry.
Design Variants：
Adjustable type: Features adjustable claws (11 mm to 54 mm) for use on a wide range of notched case backs.
Die‑type set: Includes multiple individual dies (e.g. 34 mm, 36 mm, 38 mm, 41 mm) with specific side counts; used with a separate handle or wrench.
Rugged Materials： Constructed from stainless steel or high‑strength aluminium alloy for durability and wear resistance.
Ergonomic Handle： Long handle design provides excellent leverage when opening stubborn or tightly sealed case backs.
Q1: Does this tool fit all Breitling case backs?
A： This set is designed for the polygonal (12‑sided or 15‑sided) screw‑down case backs commonly used on Breitling watches. Some vintage or special models may use different case back constructions. Please check your case back before ordering.
Q2: Should I choose an adjustable wrench or a die‑type set?
A： An adjustable wrench is more versatile for occasional use on different watches. A die‑type set provides a more precise fit and is better suited for regular work on Breitling watches.
