View source for Sinn 6052 Frankfurt Financial District Watch with calendar week display

The '''Model 6052 [[Sinn Frankfurt Financial District|Frankfurt Financial District Watch]] with calendar week display''' is an [[automatic chronograph]] from [[Sinn]] produced since [[2014]] and is the ninth model in the [[Sinn Frankfurt Financial District]] line. Like the [[Sinn 6099|Model 6099]] introduced the same year, it brought the [[chronograph]] complication to the larger case.

==Overview==
In [[1999]], [[Sinn]] added a model to celebrate the company's home city of Frankfurt and to appeal to the business and finance professionals there. The Frankfurt Financial District Watch was designed to reflect the sensibilities of the German businessman, with clean utilitarian lines, a restrained black dial, and stainless steel case. And, reflecting the international appeal of Frankfurt, the Frankfurt Financial District Watch was designed to show the time in multiple timezones. The company suggested that it could keep track of the time in New York and Tokyo, two other major stock exchanges, while showing the local time in Frankfurt.

The original [[Sinn 6000|Model 6000 Frankfurt Financial District Watch]] used a 38.5 mm case, which was up-sized in [[2014]] for the 41.5 mm [[Sinn 6099|Model 6099]]. This '''Model 6052''' was launched one month later and shares the new, larger case but uses a different movement with dramatically different features.

Model 6052 is the first "Frankfurter" to use [[Sinn calibres|a Sinn movement]]: [[SZ03|Cal. SZ03]] is based on the [[Valjoux 7751]] but is modified in many ways. The 30 minute chronograph counter is replaced by a Sinn-designed 60-minute counter at 12:00. The 12 hour counter traditionally placed at 6:00 on the dial is replaced with a [[week number indicator]] using a [[pointer]] in a [[subdial]]. The rotating inner bezel used to show a third timezone on most Frankfurter models is gone, replaced by a date scale for the [[date by pointer|centrally-mounted date pointer]]. The crown at 10:00 is also gone, with a [[corrector]] added for the [[annual calendar]], which displays [[day]] and [[month]] in windows inside the 12:00 subdial. The [[Small seconds|running seconds]] subdial remains at 9:00 but is de-emphasized with no numerals used. This is the first Frankfurter model without a [[GMT]] or [[second time zone]] display.

[[As of 2019]], only a single version of Model 6052 has been issued. A [[stainless steel]] case is paired with a electroplated black dial with a sunburst pattern. The similar [[Sinn 6012|Model 6012]], launched in [[2019]], uses a different movement with a [[moon phase indicator]].
