watch screwdriver

Common tip types include Phillips, flat/flathead, Torx and Pentalobe. Some sets also list very small bit sizes (for example 00, 0, 1) for tiny Phillips and flathead screws.

Product details list several materials: S2 alloy, bearing steel, chromium‑vanadium (Cr‑V or CRV) alloy steel, hard‑tempered black‑oxide shafts, chromed steel and general steel alloys or metal construction.

Common handle features include ergonomic or anti‑slip shapes, non‑slip rubber coatings, smooth swivel or 360° rotating caps for one‑hand turning, and diamond‑shaped or full‑metal handles for extra grip.

Many listings note magnetized tips or magnetic bits, and some kits include a magnetizer/demagnetizer or a magnetizable tip to help pick up and hold small screws.

Most kits include a dedicated storage case or box. Examples in the listings are compact plastic or transparent boxes, small sturdy cases with latches, and other portable latched storage boxes for organization and transport.

Some kits include watch tools such as spring‑bar removers/tools, link removers, tweezers, pliers and small screwdrivers useful for band adjustments and accessing the case back or battery.

Listings emphasize durability and hardness, citing S2 alloy processed by high/low‑temperature forging, bearing steel with reported hardness over HRC65°, CRV/Cr‑V steel, hard‑tempered black‑oxide shafts, and other descriptions of tough or anti‑rust metal construction.
