Opening a caseback, tightening a bridge screw, adjusting a Rolex or Omega bracelet before a weekend out of Manila: anyone who looks after their own watches keeps switching between screwdriver sizes. MisterChrono Philippines now carries a quick-change watchmaker's screwdriver set: one handle and four flat blades from 1.0 to 1.8 mm, priced at ₱4,500.

One handle, four blades
The idea is simple: the handle takes quick-change tips, each fitted with a flat blade held by a small grub screw. Pull one tip out, click the next one in, and you go from 1.0 to 1.8 mm without changing tools or hunting for the right screwdriver in a stand. The knurled body gives a secure grip for fine work, and the whole set fits in a case the size of a glasses case.
What's in the box
- 1 quick-change handle with knurled grip
- 4 flat-blade tips: 1.0, 1.2, 1.4 and 1.8 mm
- 4 spare blades in the same sizes, kept in their storage tube
- 1 screwdriver (1.6 mm) for tightening the grub screws that hold the blades in the tips
- 1 clear storage case with foam insert

Ideal for Rolex and Omega bracelets
The set is particularly well suited to Rolex and Omega bracelet screws: to remove or add a link, simply pick the tip whose blade fills the screw slot, without changing handles. Handy for fitting a bracelet to your wrist at home, or for a quick adjustment after a long day in the heat, when wrists swell a little.
MisterChrono is independent of Rolex and Omega: this tool is not made or endorsed by either brand.
Choosing the right blade
The watchmaker's rule: the blade should fill the full width of the slot without overhanging it. Too narrow and it bears on a small area, slips and marks the screw head; too wide and it scratches the plate or bridge around it. The finer sizes are for the small screws of the movement, the wider ones for bridge and rotor screws. The precision-ground blades sit snugly in the slot, which reduces the risk of slipping.
Looking after it in a tropical climate
Heat and humidity are hard on steel tools, especially during the rainy season. Put the tips back in their foam slots after use and keep the case closed, ideally with a silica gel sachet inside. A blunt or chipped blade damages screw slots: the set includes one spare blade per size, so replace it as soon as the tip starts to round off, loosening the grub screw that holds it in the tip with the 1.6 mm screwdriver supplied.

Frequently asked questions
Can I use it to adjust a metal bracelet?
Yes. It is particularly well suited to Rolex and Omega bracelet screws, and works for any link held by single-slot screws, as long as you pick the blade that matches the slot. For links with screws slotted at both ends, our bracelet tools are better suited, and for Richard Mille screws, see our set of 10 Richard Mille screwdrivers.
Are the blades replaceable?
Yes. Four spare blades, one per size, come in the case.
Is it for beginners or professionals?
Both. The compact format suits the collector who services their own watches as well as the watchmaker who wants a set of flat blades always within reach.
