reference numerals in the drawings of the specification include: the novel multifunctional watch comprises an observation platform 1, an observation table 2, a fixed disc 3, a ball 4, a mark post 5, a first magnetic block 6, a second magnetic block 7, a connecting rope 8, a handheld rod 9, a supporting rod 10, a through hole 11, scale marks 12, dates 13 and an indicating line 14.

Example (b):

as shown in fig. 3, the high-precision observation device for determining time based on date comprises an observation platform 1, a post 5 detachably connected to the observation platform 1, and an observation table 2 rotatably connected to the observation platform 1 by taking the post 5 as a rotation center, in this embodiment, the observation table 2 can be a directly plastic-sealed observation image, or can be a carrier (for example, a plastic plate or a metal plate) with scales carved on the observation image, a first magnetic block 6 is fixed on the observation platform 1, a second magnetic block 7 mutually attracted with the first magnetic block 6 is fixed on the post 5, and the detachable connection of the post 5 and the observation platform 1 is realized through the magnetic attraction of the first magnetic block 6 and the second magnetic block 7. The observation table 2 is A4 size, and the height of sighting rod 5 is 40mm, and the fixed surface of observation table 2 upper surface is fixed with transparent fixed disk 3, is connected with a plurality of balls 4 along the circumferential direction rotation on the observation platform 1, and observation table 2 lower extreme and ball 4 contact. The observation table 2 is fixed with a hand-held rod 9 on the side wall.

Referring to fig. 1, a plurality of date scale lines 12 are radially arranged on the observation table 2 along the circumferential direction of the marker post 5, dates 13 are marked at the end portions of the date scale lines 12, a plurality of indication lines 14 are arranged on the date scale lines 12, the indication lines 14 include odd number indication lines and even number indication lines, the odd number indication lines and the even number indication lines are arranged in a crossed manner, the odd number indication lines refer to odd number indication lines which are separated from the first, third and fifth through holes by taking the through holes 11 as the origin (namely, the through holes 11 are marked as 0), and the even number indication lines refer to odd number indication lines separated from the first, third and fifth through holes by the same analogy, and the even number indication lines refer to odd number lines separated from the.

The lower extreme threaded connection of observation platform 1 has a plurality of bracing pieces 10, installs the spirit level on observation platform 1 (the installation of spirit level and theory of use are conventional technical means, do not need in this embodiment to describe), and 1 lateral wall of observation platform is fixed with connects rope 8, and the lower extreme of sighting rod 5 is fixed on connecting rope 8.
