Name: Sinn 6068 Frankfurt Financial District Chronograph 6068.B
Brand: Sinn
SKU: 6068.B

The 6068 is Sinn's tribute to the Frankfurt Financial District, a tool chronograph built for the professionals who work there rather than the enthusiasts who collect for prestige. Black PVD case, Valjoux 7750, and a no-nonsense 41mm diameter that means business without announcing it. This is what Sinn does best: function first, badge second.

What it is

Sinn introduced the 6068 in 2009 as part of its Frankfurt Financial District line, a series developed with the institutional community anchored in the FFD rather than the broader collector market. The FFD editions carry a professional credibility that celebrity-endorsed watches cannot manufacture: the target customer is a banker or lawyer who wants a reliable chronograph, not a conversation piece. The black PVD treatment keeps the watch understated in an environment where discretion matters.

Sinn has maintained the reference in steady production since launch, a sign that the institutional audience it was designed for continues to respond to it.

Buying notes

PVD coatings wear at contact points over years of daily use, and the 6068 is no exception. Inspect the case edges, lugs, and crown area carefully on any used example. The Valjoux 7750 is robust but its column-wheel-less design means it can feel slightly mechanical in the pushers compared to high-end column-wheel chronographs.

Verify that the chronograph resets cleanly to zero, as a worn reset hammer is a common failure point on used 7750-based pieces. Sinn's FFD editions are sold through limited channels, so authenticate purchase provenance if buying secondhand.

Market read

The 6068 trades at a modest premium over standard Sinn steel chronographs, reflecting the PVD finish and the FFD association rather than any scarcity. Secondary market pricing is generally fair: buyers are sophisticated and the reference does not carry speculative heat. New-old-stock and lightly worn examples surface periodically through German grey market dealers at reasonable prices.

Service expectations

The ETA Valjoux 7750 is one of the most widely serviced automatic chronograph movements in the world, with parts readily available and a large pool of competent independent watchmakers. Sinn recommends a service interval of approximately five years for the 7750. Full chronograph service including timing regulation runs roughly $300 to $500 at a qualified independent.

Authentication guide

Last reviewed June 2026

The 6068 is Sinn's dress chronograph in the 6000 Series, unusual among Sinn references for its two-tone dial options (black or silver). The Valjoux 7750 base with day/date is shared with the 103, but the 6068 is positioned as a smarter, dressier piece with a flat case profile.

Known reproduction risks

LOW

The 6068 has very low replica exposure. The niche dress-chronograph positioning and modest secondary market prices make it an unattractive replication target.

Applied indices replaced with printed numerals
Rotating bezel on a reference that should have a fixed bezel
Dial color inconsistent with the stated variant (black vs. silver)

Dial variants by era

toggle

Era	Description	Identifiers
2009 to present (black dial)	Matte black dial with silver chronograph registers, three sub-dials in Valjoux 7750 layout, day and date. The 6068 has a thinner and more refined aesthetic than the pilot-focused Sinn references.	"SINN" and "6068" text on the dial Three chronograph registers: 30-minute at 12, running seconds at 9, 12-hour at 6 Day and date complication at 3 o'clock area Contrasting register color against the main dial (silver registers on black main dial, or subdued registers on silver dial) No bezel scale -- the 6068 uses a plain brushed bezel without timing markings Applied indices rather than printed numerals -- the 6068 is dressier than the pilot line
2009 to present (silver dial)	Warm silver or champagne main dial with darker contrasting registers and applied indices. A dress-watch aesthetic uncommon in the Sinn range.	Silver or champagne main dial surface with matte or lightly textured finish Darker toned sub-dial registers creating contrast against the main dial "SINN" text in black or dark tone rather than white Applied indices at hours rather than Arabic numerals Date and day display at consistent position with the black dial variant

Applied indices

Original: The 6068 uses applied indices rather than printed numerals, which is unusual for Sinn. These applied markers are individually set and should have consistent height and surface finish across all positions.

Replacement tells

Any index that sits lower or higher than its neighbors -- height consistency is the tell for genuine applied indices vs. replacements
Index color or finish different from its neighbors under the same light source -- a replaced index will not match the aging character of the originals
Printed numerals on a stated 6068 with applied indices -- indicates a non-original dial

Plain bezel

Original: Fixed, plain brushed steel bezel without scale markings. No rotation. This is the dress-watch approach for the 6068, distinguishing it from the pilot line.

Replacement tells

Bezel that rotates -- the 6068 has no bezel rotation function
A bezel with scale markings (tachymeter, telemeter) from a different Sinn reference fitted to the 6068 case
Bezel surface with polished facets inconsistent with the brushed steel specification

Case back markings

toggle

2009 to present

"SINN SPEZIALUHREN" and "GERMANY"
"6068" reference and "Frankfurt Financial District" text (on some variants)
"WATER RESIST 200M" depth rating
Serial number on case band

Movement tells

toggle

Valjoux 7750 beats at 28,800bph, 42-hour power reserve. A fully wound 6068 stopping before 36 hours warrants service.
Day and date should advance together at midnight. Gradual advance or misalignment between day and date indicates worn quickset mechanism.
Chronograph hands should reset to zero simultaneously with a single pusher press. Sequential or sticky reset indicates worn heart cams.
