BilliB clocks have all or some of the following:
- 35 punched & enlarged oil cups = punching hardens the brass plate and increases oil capacity promoting longer movement life.
- Four jewels, on some movements = Jewels require very little lubrication and will hold closer tolerances. (jewels are not used on large gears as they would crack under stress)
- Nine bronze bushings on some movements = bronze is stronger & harder than common alloys apart from steel but exceeds steel in corrosion resistance and ease of lubrication. (source Funk & Wagnalls)
- Six bronze bushings strategically placed result in the gears moving against highly polished pinion steel in a bronze bushing is known as the best combination for minimising movement wear. (source Funk & Wagnalls)
- Pivot inserts made of ball bearing steel = minimal movement wear
Superior Sound and Advantages
- Redesigned governor fan = even speed
- Increased cylinder drum diameter = better cadence
- Larger heavier hammer heads = hits the rods with more force
- Increased hammer lift = Easier to adjust chime/strike hammers for fine-tuning.
Servicability and Advantages
- Marked alignment indicators on stop gears
- Easy to move winding arbors
- Re-usable washers / c-clips
- Cable where fitted is tested to as high as 80 pounds =offering strength and longevity
- Power maintaining feature on some movements =continues to keep correct time, when clock is being wound up
- Electronic friction testing = less friction longer movement life
Cabinets
- Full Pediment Return = even finish aesthetically pleasing
- Thickness of clock backs = adds strength whilst helping to prevent timber movement in modern heated homes.
- End frame thickness = (quality construction)
- Dial surround frames = promotes sound quality whilst helping to prevent dust entering the movement
- Quality Dial
- Door thickness
- Quality finish
- Locks and Keys
