This makes it a practical choice for hobbyists who repair a mixed collection of clocks or for a workshop where quick size changes are common.

Brass Blessing: 5 Prong Brass Clock Key (5023)
This model focuses on five odd-numbered prongs, including sizes 3mm, 3.5mm, 4mm, 4.5mm, and 5mm. It’s ideal for clocks that use non-even winding keys or when you need a precise odd-numbered fit. Best for: antique clocks or collectors with odd-size winders. Limitation: odd sizes may not fit standard modern winders.
2 Pieces 5-in-1 Odd/Even Brass Clock Winding Key
This set includes two keys covering both odd and even five-prong sizes. It provides broad compatibility with many classic clocks and offers a cost-effective option for busy repair tasks. Best for: workshops needing rapid access to multiple prong configurations. Limitation: the outer shape may not suit all non-standard winders.

Best for: antique or floor clocks with larger winding holes. Caution: not all smaller desk clocks will require these sizes.
TAURISH Universal Vintage Clock Winding Key
This five-prong key covers sizes 2 to 10 in one universal tool, offering broad compatibility for many vintage clocks. It’s a solid choice for those who want a single solution instead of multiple keys. Best for: collectors seeking a versatile, all-in-one option. Limitation: as a universal tool, it may be slightly bulkier for very small cases.
Buying Guide
- What winding size does my clock require? Start by measuring the winding arbor or examining the square-hole size. Brass keys typically list sizes in millimeters and fractional inches (e.g., 2.75mm, 1/8 in). Choose a key that matches or sits very close to the clock’s requirement.
- Odd vs. even prongs: Some clocks use odd-numbered prongs while others use even. If you own multiple clocks, consider a 5-prong kit that includes both odd and even sizes, or a universal set.
- Material durability: Brass keys resist wear and corrosion, maintaining a precise fit over time. For antique or vintage clocks, brass keys help preserve the delicate arbors.
- Number of keys: A two-pack or a five-prong set can reduce the need to swap keys frequently. Consider a kit that covers the majority of your collection to streamline repairs.
- Compatibility and scope: If you repair many different clocks (floor, wall, mantel, pocket watches), prioritize universal or multi-size kits to maximize compatibility.
- Size accuracy: Look for clearly listed hole measurements (outer/inner diameter) to ensure a proper fit and avoid damaging the winding mechanism.
- Maintenance approach: Keep keys clean and dry to prevent brass corrosion and ensure smooth operation when winding.
