Revue started production of the calibre 59 in 1937 as a replacement to their calibre 56. The 59 was similar in design, but overall a larger movement. The basic model is not shock protected, but most variants had inca shock as standard. The most common variant is 26.5mm, but there also exists a wider variant (I’m currently missing exact size). There is also a centre second variant.
