Both watches from the top. Although the Loga seems much shorter from lug to lug, the difference is only 3.5 mm. Note that both watches have been resized for my 6.5 inch wrist. Noticeable also the large knurled section on the bezel of the Loga that makes using the slide-ruler so easy. That the crystal runs together with the outer slide ruler scale is quite unusual. Normal these scales are operated via crowns. This and the beautifully designed Loga dial were the reasons I bought this watch.
