2pcs 4040, 4039 Copper Movement Holders

Description

These two precision copper movement holders (models 4040 and 4039) bring rock-solid stability to your bench, letting you clamp calibers from approximately 9 mm all the way up to 45 mm without worrying about slips or scratches. Machined from copper, each reversible jaw set grips common workhorse movements. Think ETA 2824, Valjoux 7750, Seiko NH35, Miyota 8215 and similar, so you can disassemble, oil and reassemble with both hands free and complete confidence.

• 4039 is the small-range holder, designed for movements from roughly 3¾ ligne (≈9 mm) up to 11 ligne (≈25 mm). Its jaws open from about 6 mm to 20 mm, making it ideal for smaller calibers like ladies’ ETA or slim mechanical movements  .

• 4040 is the large-range holder, covering movements from about 8¾ ligne (≈20 mm) up to 19 ligne (≈43 mm). Its jaws open from roughly 8 mm to 30 mm, accommodating full-size men’s and larger automatic calibers
