Key Highlights
- BREMONT assemblers keep nine screwdrivers on the workbench, each colour-coded to indicate its size.
- Different watch models require different screw sizes — the Altitude 40 range uses larger screws, the Altitude 39 range uses smaller ones.
- Some screws inside BREMONT watches are as small as a grain of rice.
- Every screw is driven entirely by hand — no machinery is used in the screwing process.
- All assembly work takes place within BREMONT’s dedicated assembly room.
The Quiet Discipline Behind Every BREMONT Case
There is a moment during watch assembly that most enthusiasts never witness: the precise selection of a single screwdriver from a row of nine, each marked with a different colour, before a component barely visible to the naked eye is fastened into place. This is not theatre — it is a functional necessity born from the realities of mechanical horology. BREMONT, the British watchmaker known for its technically demanding builds, offers a candid look at why that tool selection matters far more than it might first appear.
Precision in watchmaking is not a marketing abstraction. Inside any mechanical watch, the screws securing bridges, plates, and complications are engineered to exact tolerances. Using a blade that is even fractionally too wide or too narrow risks damaging the screw head, misaligning the driver’s torque, or worse, compromising the integrity of a component that took hours to position correctly. The colour-coded system BREMONT employs is a practical solution to a very real problem — it eliminates guesswork at the bench and keeps the assembly process both efficient and safe for the movement.
For collectors across the GCC who appreciate the depth of craft behind their timepieces, this kind of behind-the-scenes transparency is particularly valuable. Understanding why a watchmaker reaches for a specific tool illuminates the full weight of what “hand-assembled” actually means — and reinforces the considerable skill required at every stage of production.
Nine Screwdrivers, Two Altitudes
The practical reason for maintaining nine separate screwdrivers comes down to the range of models BREMONT produces. The Altitude 40 and the Altitude 39 — two distinct references in the brand’s lineup — are built around different case dimensions, and those dimensional differences cascade all the way down to the smallest internal hardware. The Altitude 40, with its larger architecture, accommodates larger screws; the Altitude 39, being the more compact reference, is fitted with correspondingly finer fasteners throughout.
This is not a trivial distinction. A screwdriver blade must match the slot width and depth of the screw it engages with remarkable accuracy. Too large a blade will slip and mar the screw head; too small and it will lack the surface contact needed to apply even torque. By colour-coding each driver to its size, the assembler can move through the work with confidence, reaching for the correct instrument without interruption to their focus or workflow. It is a small organisational discipline with significant consequences for the finished watch.
Screws the Size of a Grain of Rice
Among the most striking details to emerge from BREMONT’s assembly room is the scale of some of the components involved. Certain screws used in these watches are, by the assembler’s own account, no larger than a grain of rice. At that dimension, the margin for error is essentially zero — an incorrect driver, an unsteady hand, or a momentary lapse in concentration can render a component unusable. The fact that each of these fasteners is driven manually, without the assistance of any automated machinery, underscores the degree of skill required of BREMONT’s bench technicians.
This commitment to hand assembly connects directly to BREMONT’s broader manufacturing philosophy. Pieces such as the Supernova 41mm Tourbillon and the Moon Mission I represent the more technically elaborate end of that same ethos — complex movements where the manual handling of micro-scale components is not a heritage affectation but an operational requirement. The nine-screwdriver system seen in the Altitude range is, in essence, the same discipline applied at every tier of the collection.
Tools as an Expression of Craft
It is easy to overlook tooling when discussing watchmaking. Conversations naturally gravitate toward movements, complications, and finishing — the elements that are visible and photographable. But the tools a watchmaker selects are, in their own way, as telling as the components they handle. A bench equipped with nine carefully differentiated screwdrivers, each assigned a specific colour and purpose, speaks to a working environment where nothing is left to improvisation and every variable has been considered in advance.
For watch collectors in the Gulf — where BREMONT has cultivated a following among enthusiasts who value technical substance over purely aesthetic appeal — this kind of craft transparency resonates. The region’s collector community increasingly seeks access to the story behind the dial, and footage of an assembler articulating why each tool on the bench exists answers exactly the questions serious buyers tend to ask. It reframes the watch not as a finished object but as the outcome of hundreds of deliberate, considered decisions made by hand.
Why It Matters
For GCC collectors investing in a BREMONT timepiece, the nine-screwdriver system is a tangible symbol of the precision and accountability built into every watch that leaves the assembly room. It confirms that hand assembly at BREMONT is a structured, tool-disciplined process — not simply a label. Enthusiasts who value the full story of their timepiece will find this level of craft transparency both reassuring and compelling.

Frequently Asked Questions
Why do BREMONT watch assemblers use multiple screwdrivers?
BREMONT assemblers use nine colour-coded screwdrivers because the watches come in different sizes and each watch contains screws of varying dimensions. The colour coding allows technicians to select the correct tool instantly for each component.
What is the difference between the BREMONT Altitude 40 and Altitude 39 in terms of assembly?
The BREMONT Altitude 40 range features larger screws that require the bigger screwdrivers, while the Altitude 39 range uses smaller screws that demand the finer, smaller tools in the assembly set.
Are BREMONT watches assembled by hand or by machine?
BREMONT watches are assembled entirely by hand. Even screws as small as a grain of rice are driven manually by skilled assemblers working in the assembly room, with no machinery involved in the screwing process.
