Let me offer you one phrase that issues for the corporate and followers of the model: Einsatzzeitmesser, or ought to I say EMZ. Now issues ought to grow to be a bit clearer for you, as there’s a great motive why, when these new Sinn 613 St and 613 St UTC fashions, they may ring a bell. What we’re are flipped variations of the basic EZM 13 or mission timer watch. The EZM watch by Sinn is, along with the U1 dive watch and the 104 pilot’s watch, certainly one of its most revered and sought-after watches. The idea is now again in a reasonably extra basic duo, with the crown within the basic place, a day-date complication and a few contrasting colors on the dial. However the principle recipe of a software watch combining capabilities continues to be there.
The unique EZM 1 of 1997 was one of many cleanest and most legible diving chronographs that involves thoughts. Utilizing two central chronograph fingers (for the seconds and minutes) and no sub-counters, it had a 60-minute pilot’s countdown bezel, a titanium case, and a left-sided profile with a crown and pushers at 9 o’clock. Inside was a Lemania 5100, and following the top of its manufacturing, the watch was discontinued within the late 2000s. It was initially designed for particular German Customs Forces and later turned obtainable to most of the people. The model later launched the EZM 3, a extra basic (no chronograph) dive watch, and the EZM 13 in 2014. And in 2022, the idea got here again with the EZM 13.1 Diving Chrono – the 2 extra fashionable variations, nevertheless, utilizing a distinct show with a 60-minute sub-dial.
The brand new Sinn 613 St – subsequent to its multi-time-zone counterpart, the 613 St UTC – is basically a flipped model of the EZM 13.1 Diving Chronograph with destro model. I’m saying basically, as there’s a bit greater than meets the attention. The general design, specs and dimensions stay equivalent. The bead-blasted, ultra-matte stainless-steel case measures 41mm in diameter, 15mm in thickness and the watch head is about 98 grams. Not a small watch, however remember the fact that we’re a critical aquatic software able to withstanding 500m of depth. The remainder: sapphire crystal with double-sided AR coating; righ-positioned screw-down crown and pushers with D3-System; screwed caseback; “captive” rotating bezel (60 clicks) with black aluminium insert and 60-minute scale. A standout characteristic is the Ar-Dehumidifying Know-how, making certain enhanced useful reliability and freedom from fogging. Moreover, magnetic discipline safety as much as 100 mT (80,000 A/m) successfully prevents magnetization… Basic German over-engineering – and it meets DIN 8310 and 8306 norms.
Wanting on the dial, there are extra modifications than on the case, but the fundamentals are nonetheless there. Matte black base, giant painted and luminous markers, clear white lumed fingers… The show of the Sinn 613 St is, nevertheless, pretty completely different from that of the EZM 13.1. First, the working seconds has been relocated to 9 o’clock, which by the way leaves house for a extra balanced date window at 3 o’clock (it was at 4h30), and now subsequent to it’s a day-of-the-week indication. Subsequent, whereas the 60-minute sub-register continues to be positioned at 6 o’clock, it has right here been white-coloured for a contact of distinction and a extra fashionable look. The show is actually crisp and clear, with the small seconds barely seen and used largely at a working indicator (a necessity for a dive watch).
There may be additionally a model new mannequin within the assortment, the Sinn 613 St UTC Diving Chronograph. What adjustments right here? Properly, concerning the case, the specs and the general structure of the dial; nothing. The primary distinction is that the day-of-the-week indication has been eliminated (solely the date stays) and changed by a fourth central hand that acts as a second time zone on a 24-hour foundation (independently adjustable) and painted in darkish gray to keep away from it taking an excessive amount of consideration.
Each the Sinn 613 St and the 613 St UTC fashions run on the calibre SZ02, an inside identify for modified Valjoux-based computerized chronograph motion produced by Sellita. That being mentioned, there are some essential modifications, such because the 60-minute recorder and the addition of the UTC operate. These actions run at 28,800 vibrations/hour, boast 42 hours of energy reserve and have a basic cam-lever chronograph mechanism. These are hidden below screwed caseback.
These two fashions can be found on a choice of 20mm leather-based or silicon straps, in addition to a bead-blasted stainless-steel bracelet. Certainly, these two new Sinn 613 St and the 613 St UTC Diving Chronographs usually are not revolutionary however, in all equity, symbolize what Sinn does greatest. Strong, targeted and strongly constructed watches for a mission. The 613 St is offered now from EUR 2,450 (leather-based/silicon) or EUR 2,800 (metal bracelet), and the 613 St UTC from EUR 2,950 (leather-based/silicon) or EUR 3,300 (metal bracelet).
