Located at the top of the dial, just beneath the 12 o’clock hour marker, is a large double-window big date aperture that displays the day of the month with a large serif-style typeface. Directly beneath the big date window is the A. Lange & Sohne branding just above the center pin of the hour and minute hands.
A remarkable mechanical feature of the sub-dials is that each of the three sub-registers has a double function cheap replica watches. Let us get a bit more granular about each of the functions found within each of these smaller dials.
3 o’clock position: The sub-register on the right essentially has two sub-dials to it. One shows which month it is with a small, polished hand. It also has a smaller “sub-sub” dial in a contrasting color that shows which year in the 4-year cycle for the leap year we are holding in. The advantage of a perpetual calendar is that the date does not need to be reset every four years the way an annual calendar watch would. In the negative space located at the upper center of this sub-dial the words ‘perpetual calendar’ are printed.
The 6 o’clock position: This sub-register is a window for a moon phase disc and has an integrated small running second’s dial that uses a combination of Arabic style numerals for the 20-second, 30-second, and 40-second positions and fine-printed indices on the second’s track, indicated with a slender polished hand. The word SAX-O-MAT, referring to the movement, is printed in the negative space of this sub-dial.
The Langeamtik collection has a history of giving birth to many impressive watches and this is to be expected from a top-shelf watchmaker like Lange. The exact model from this collection that we will be looking at today is reference 310.026 that is an 18kt white gold model that comes on a black leather strap. Let us dissect this watch piece by piece to get as granular as possible and not leave any stone unturned.
The watch features a matte black dial with a step-down center circle that passes through three sub-dials ozcatalyst.org. The functions of these sub-dials will be explained after we cover the main dial that tells the time.
The main dial has a printed railroad-style seconds track that runs around the perimeter of the dial. Inside the second’s track are luminous dots at each hour marker/five-minute interval with a double luminous dot is at the twelve o’clock position.
A combination of styles was used for the applied and polished hour markers: Roman numerals are used for 10, 11, 12, 1, 2, 5, and 7 o’clock positions and index-style hour markers are used for the 4 o’clock (singe index), 6 o’clock (double-index) and 8 o’clock (single-index) positions. The 3 and 9 o’clock positions do not use any applied hour markers since that area is occupied by the sub-dials on the right-hand and left-hand side of the dial.
