MKS 15710 Kizumi Watchmaker's Loupe No. 2.0 (approx. 6.0x) – Eye Loupe for the Finest Detail Work | Meikosha, Made in Japan

Original watchmaker's tool from MKS (Meikosha) from Nagoya, imported directly from Japan – not regularly available in Europe.

The Kizumi (キズミ) is the classic Japanese watchmaker's eyeglass loupe – the first tool every Japanese watchmaker reaches for. The MKS 15710 is the standard Kizumi in Japanese workshops: lightweight, matte-black body that sits securely and comfortably in the eye socket, with a cleanly ground lens free of edge distortion.

The No. 2.0 is the strongest magnification in the series (approx. 6.0x; the number, according to old watchmaking tradition, indicates the focal length in inches – the smaller the number, the stronger the magnification). It is the loupe for the finest work on the movement: checking pivots and jewels, assessing hairsprings, inspecting the escapement, setting the finest screws and springs. The short working distance brings the eye close to the detail – where the decision for a successful overhaul is made.

What distinguishes this tool from European counterparts:

Functionally, the Kizumi is equivalent to the well-known Swiss eye loupes (Bergeon 4422 and similar) – the difference lies in fit and weight: The Japanese shape is cut flatter and sits much more securely on many face shapes without a retaining wire or straining the eye area. In Japan, the Kizumi is part of the official tool lists for the state watchmaking examination; the MKS version is the common professional quality there. Anyone who has ever worked with a poorly fitting loupe knows: The fit is crucial for fatigue-free work.

The series includes three magnifications: No. 2.0 (approx. 6.0x, this listing), No. 2.5 (approx. 5.0x), and No. 3.0 (approx. 4.4x) – all available individually in our shop.
